Ordyne/Gameplay

Controls

 * Joystick: Use the 8-way joystick to direct Yūichirō (or Sunday, if you're player 2) around the screen; they are always moving forward, but you can direct them anywhere. If one of them flies into Miyuki Chan's Kūchū IN or into Dream Co., Ltd. the other one will automatically be drawn in as well.
 * Firing Button: Use this button to make Yūichirō (or Sunday if you're player 2) fire shots at the enemies; they will never run out of the normal ones.
 * Bomb Button: Use this button to make Yūichirō (or Sunday if you're player 2) drop bombs on the enemies; they will never run out of normal ones.
 * 1 or 2 Player Buttons: Push these buttons to begin a 1 or 2 player game.

Yūichirō Tomari (泊裕一郎)
The genius scientist who flies a red ship and is controlled by the first player; along with his Chinese assistant Sunday Chin, he is on a mission to rescue his kidnapped fiancee, Kana Aihara. He will lose one life, and any special weapons he may have had, whenever he gets hit by an enemy or anything that is fired at him by one - but if he had won a special weapon from Dream Co., Ltd. earlier and turned it down he will receive it at that point.

Sunday Chin (サンデーチン)
Yūichirō's Chinese assistant, who flies a green ship and is controlled by the second player; he can join a game already in progress at any time, and will receive 5000 free crystals if he does so. However, his presence will cause all projectile-firing enemies to fire twice as many projectiles, and all bosses to take twice as many hits to kill - so you should keep this in mind, if you are ever planning to play this game with a friend at some point.

Kana Aihara (相原香奈)
Yūichirō's kidnapped fiancée, who appears in the background at the end of the seventh round after Dr. Kubota has been defeated; in the ending sequence, Yūichirō and Sunday let her have the honour of firing a shot at Dr. Kubota's space station to burn it up and transform it into a volcanic explosion cloud. All three of them will then fly into the explosion cloud, which carries them back down to Earth - and she later became the fifth pitcher for the Nikotama Gals in Super World Stadium '99, the last title in Namco's long-running World Stadium series, which had began earlier in this game's year.

Miyuki Chan (みゆきちゃん)
This blue-haired woman sells special weapons and extra lives (in exchange for crystals), at the "Kūchū IN" (空中IN) which will fly by twice upon the first, second, third and sixth rounds and once on the fourth, fifth and seventh rounds; when one player enters it, the other will automatically be drawn in as well and she will speak the Kanji/Hiragana text of: ''Irasshaimase Kūchū IN he yōkoso. 1P/2P no kata ue no naka kara 1 tsu dake erande kudasai.'' (いらっしゃいませ空中INへようこそ. 1P/2Pの方上の中から1つだけ選んで下さい.) to them, and they will have 20 seconds to choose one of the three items shown on the screens in front of them. There are a total of ten different items here and here is a list of them and what they do:
 * Vulcan shot (バルカンショット): These shots are fired from Yūichirō's (or Sunday's) ship at a faster rate.
 * 3-way shot (3-WAYショット): These shots are fired from Yūichirō's or Sunday's ship, in three directions.
 * Wide shot (ワイドショット): These shots are wider (and five times more powerful) than the normal shots.
 * After shot (アフターショット): These shots are ten times more powerful than normal shots and are fired continuously from both the fronts and backs of Yūichirō's (or Sunday's) ships; this is an especially useful shot to have when it comes to the bosses (as you will easily be able to defeat them with it).
 * Stock bomber shot (ストックボンバーショット): Pac-Man will be held in place upon the front of Yūichirō's or Sunday's ship with a green claw, create a shield around it, suck in all the projectile-firing enemies' shots and spit them back out at them; the more shots he sucks in, the bigger he will become, and the more powerful the shots he spits out will be. Only one player can have this special weapon at any time - if the other player wishes to buy one from Miyuki or wins one from Dream Co. Ltd., they will simply refuse to give it to him, by speaking the Kanji/Hiragana text Kurisutaru ga tarimasen (クリスタルが足りません) or Zan'nen da!! Deha mata (残念だ!! ではまた), which are this game's standard "Not enough crystals" and "Answer of no" texts. Unlike all the other types of special shots which will only last until Yūichirō and Sunday's "Weapon" meters at the bottom of the screen are empty (or they get killed), this one will last them until its shield is either penetrated by something that is not a projectile or they get another type of special shot; however, if whatever penetrated the shield is still in contact with either Yūichirō or Sunday's ship when the shield disappears, it shall cost them a life.
 * Fire bombs (ファイヤーボンブズ): These bombs will create a huge explosion upon impact and are especially useful against Power Station and R-4B.
 * Homing missiles (ホーミングミサイルズ): These bombs will automatically home in on any enemies currently on screen; the missiles that the Perikan and Dr. Kubota's machine spit from their mouths are also similar to them, but they can be blocked by one of your own shots for 50 extra points each.
 * Subroc bombs (サブロックボンブズ): If you wish to to exchange your crystals for these bombs on the third and fourth rounds you have to be playing as Sunday (player 2); they will fly into the air and create a small explosion upon impact, but are not particularly useful (unlike the other two choices). All types of special bombs will last Yūichirō and Sunday for five uses (which are indicated by the five grenade symbols that are displayed to the right side of the aforementioned "Weapon" meters, and one of them will disappear each time they drop one) or until they are unlucky enough to get killed.
 * Speed-ups (スピードアップス): These will increase the moving speed of Yūichirō's (or Sunday's) ships until they are unfortunate enough to get killed.
 * Extra lives: Extra lives can be obtained in exchange for crystals in this game, along with that usual way: accumulation of certain point values (which are 40,000, 120,000, and 220,000 by default); once you have pressed that Firing Button to confirm your choice, Miyuki will speak the Kanji/Hiragana text Arigatōgozaimasu XX000 (XX being a number which can range between 2 and 998) kurisutaru desu. Mata no o raiten wo omachi shite orimasu. (有難うございますXX000クリスタルです. またの御来店をお待ちしております.) to Yūichirō and Sunday, and they will now exit the Kūchū IN and continue. It is also worth noting that she refers to her store as the Suichū IN (水中IN) for the two occasions it passes on that third round, rather than Kūchū IN.

Dream Co., Ltd. (夢有限会社)
This big white-handed robot will fly by once on the second, third, fourth, fifth and sixth rounds; as with the Kūchū IN, when one player flies into him, the other will automatically be drawn in as well, and he will speak the Kanji/Hiragana text Watashi ha DREAM CO., Ltd. X000 (X being a number which can range between 1 and 5) ''kurisutaru ī mono ga ataru yo. 1P/2P no kata chōsen shite mina ika?'' (私はDREAM CO., Ltd. X000クリスタルいいものが当たるよ. 1P/2Pの方挑戦してみないか?). If either of the players' answer is "yes", he will extend his target and speak the Kanji/Hiragana text of Yō shide ha 3-byō-go ni botan wo sunda!! (よーしでは3秒後にボタンをすんだ!!) as it starts rotating (providing you had enough crystals to pay him) - and after 3 seconds, you must push the Firing Button to launch a marble at the target. The table on the left side of the screen shows what you will win for each number (with the special weapons' names in Katakana), and once the target has receded again, he will speak either the Hiragana text Omedetō!! (おめでとう!!) if you won or the Kanji text Zan'nen (残念) if you lost; if you won a special weapon, he will speak the Kanji/Hiragana text Kono buki ha sugu tsukaimasu ka? (この武器はすぐ使いますか?), and if you answer "no" you'll receive it the next time you get killed. This is especially useful if you win an After shot from him, turn it down and die just before the final battle with Dr. Kubota, as you will easily be able to defeat him with this special weapon - and he will now speak the Kanji/Hiragana text Mata no chōsen wo matsu teru yo. (またの挑戦を待つてるよ) to Yūichirō and Sunday, before they exit his realm and continue onward. The five Kanji characters in his name also literally read as Yume Yūgengaisha.

Crystals (クリスタルズ)
Crystals are the units of currency in this game; they can be obtained by killing a group of smaller enemies, killing some larger enemies, through Dream Co., Ltd., and by clearing a round. The amount of crystals you have remaining after defeating Dr. Kubota at the end of the seventh round will also be added to your score as bonus points - which, combined with the 20000 for every life you have remaining, could add to a very high final score.

Hanbaga (ハンバーガー)
These hamburger-like robots appear in groups of five on the first, second, fourth and sixth rounds, and attack by flying towards Yūichirō and Sunday in a zigzagging pattern; they are worth 100 points, and when all five have been killed they will leave a 1000 Crystal behind.

Heri (ヘリ)
These helicopter-like robots appear on the first, second, fourth and fifth rounds, and attack by flying towards Yūichirō and Sunday while firing projectiles at them; they are worth 100 points. The big ones start out as gray blobs, attack by firing missiles at Yūichirō and Sunday (once they have fully materialized) and are worth 1500 points - and when one gets killed, it will leave several Crystals behind.

Aka Hikoki (赤飛行機)
These aeroplane-like robots appear on the first and sixth rounds, and attack by firing projectiles at Yūichirō and Sunday once their side-mounted guns have stopped rotating; they are worth 300 points, and the ones that appear on the sixth round are a darker shade of red.

Kame (カメ)
In the first round, these turtle-like robots will attack by emerging from the clouds in groups of five and flying directly towards Yūichirō and Sunday while firing projectiles at them; they are worth 100 points, and when all five of them have been killed they will leave a 1000 Crystal behind. In the sixth round, however, they serve a rather different purpose - and you should scroll down to the section on Power Station for more information about this.

Same (サメ)
These shark-like robots appear on the first round and attack by leaping up into the air in order to drop down on Yūichirō and Sunday; 100 points.

Kuchu Yosai (空中要塞)
This aerial fortress appears at the start of the first round, and will come down on Yūichirō and Sunday from above (in an attempt to crush them); later on, it will come up on Yūichirō and Sunday from below while firing projectiles at them, and you should try to bomb as many of its five roof-mounted projectile-firing cannons as you can at this point for 100 points apiece. At the end of the round it must be fought as a boss - you should try to destroy the projectile-firing cannons on its front first, then aim for its core. Each of the three projectile-firing cannons on its front are worth 100 points and the core is 5000; once you have fired enough shots at that aforementioned core to destroy it, that "stage clear" theme will be heard from the Yamaha YM-2151 for the first time as it explodes and sinks beneath the surface of the clouds; it also reappears at the start of the sixth round (but not as a boss this time) and will fly around the screen in an anticlockwise direction while firing projectiles at Yūichirō and Sunday from all around. All of its five roof-mounted projectile-firing cannons can also again be destroyed for 100 points apiece.

Ropera (ロペラ)
These robots, which are named after Lopera (a city in the province of Jaén, Spain), appear on the second round in groups of six and attack by coming down from the top (and up from the bottom) of the screen while flying directly towards Yūichirō and Sunday; they are worth 100 points, and when all six of them have been killed they will leave a 500 Crystal behind. They will also speak "Ropera, ropera, rope-rope-ropera" from the C140.

Juden Iruka (放電イルカ)
These dolphin-like robots appear on the second round and attack by dropping down from above in front of Yūichirō and Sunday to fire projectiles at them; they are worth 700 points, and when one is killed, he will leave a 500 Crystal behind. "Juden" also literally means: "electrical discharge".

Kaiten Meiro No Taiho (回転迷路の大砲)
These circular cannons appear in the rotating mazes on the second and seventh rounds, and attack by firing projectiles at Yūichirō and Sunday; they are worth 500 points. Also in that seventh round, firing a shot at a block with a blue arrow on it will increase the speed of the rotating mazes, a broken blue arrow on it will decrease the speed of the mazes and a block with a red arrow on it will reverse the rotating direction.

Kiwi (キウイ)
These fruit-like robots appear on the second, fourth and seventh rounds; when Yūichirō and Sunday approach their bases (which are worth 500 points), they will open up, and the Kiwi inside (which are worth 50 points) will be released in groups of four, flying directly towards Yūichirō and Sunday once they have reached their altitude. The bases will also never stop releasing them until their deaths so they are a source of infinite points.

Ao Tanks (青タンクス)
These beetle-like robots appear on the second, fifth and seventh rounds, and attack by firing five projectiles at Yūichirō and Sunday; 500 points.

Wani (ワニ)
These crocodile-like robots appear on the second and seventh rounds and attack by homing in on Yūichirō and Sunday in order to eat their ships before pulling back up for a second attempt; they are worth 2000 points, and when one is killed, he will leave several Crystals behind.

Fire Tortoise (ファイヤートータス)
This flaming sub-aquatic reptile is the boss of the second round; he will emerge from the lava and start shooting fireballs at Yūichirō and Sunday (which can be blocked by your own shots, for 10 extra points apiece) while hovering in place, then curl up into a ball and fly round the screen while shooting fireballs at Yūichirō and Sunday from all directions before coming back out of the ball and repeating his pattern. Once you have fired enough shots at him, to defeat him (he is worth 5000 points), any fireballs that are on the screen will explode and the "stage clear" theme will be heard from the Yamaha YM-2151 for the second time as he shrinks and falls back into the lava; by catching him, you will earn a random amount of bonus points that ranges from 1000 to 5000 (it will be shown in red if it was Yūichirō who caught him and green if it was Sunday). He also reappears in the sixth round after Kuchu Yosai has flown away off the left side of the screen, but is coloured blue (instead of orange) and moves much faster than before.

Sensuikan (潜水艦)
These submarines appear upon the third and fourth rounds, and attack by firing missiles into the air (which will explode at a preset altitude, and can be blocked by your shots for 50 extra points apiece); they are worth 1500 points themselves, the same as a not-yet-seen Big Heri.

Maru Hodai (丸砲台)
These spherical cannons appear on the third, fourth and seventh rounds, stay perfectly lined up with Yūichirō and Sunday's positions when they are passing over them and attack by firing projectiles at them; they are worth 50 points, but some of them cannot be killed without the After shot.

Sora Yu Kirai (宇遊機雷)
These large mine-like robots appear on the third round and attack by moving left and right while going up and down; they are worth 2000 points.

Gyorai (魚雷)
These small mine-like robots appear on the third round and attack by dropping down on Yūichirō and Sunday as they pass under them; 500 points.

Kingyo (キンギョ)
These goldfish-like robots appear on the third round, attack by firing projectiles at Yūichirō and Sunday, and are accompanied by small Sakana (see the section below); they are worth 300 points, and when they (and their two escorts) have been killed, they will leave a 500 Crystal behind.

Sakana (サカナ)
These fish-like robots, which come in two sizes, appear upon the third round and attack by firing projectiles at Yūichirō and Sunday; 100 points.

Power Station (パワーステーション)
This industrial generator is the boss of the third round; it attacks by moving up and down while spewing fireballs at Yūichirō and Sunday (which are different from those of Fire Tortoise, but can still be blocked by your own shots, for 10 extra points apiece), and its weak points are the balls in its rotary mechanism (which are worth 500 x 8 points). However, if you should take too long over destroying them, it will start moving to the sides as well - so if you are player 1, you should try to avoid these situations by choosing that After shot from Miyuki Chan's Kūchū IN beforehand (if you are player 2, you will have to win it from Dream Co., Ltd., if you want it in this fight) beforehand. The "stage clear" theme will then be heard from the Yamaha YM-2151 for a third time as it sinks below the surface of the ocean; it also reappears upon the sixth round, but spews Kame instead of fireballs, which will fly directly at Yūichirō and Sunday once they have reached their altitudes (this is their other purpose). It can also reach to the top of the screen.

Tako (タコ)
These octopus-like robots appear upon the fourth round and attack by moving up, then pausing before moving down; they are worth 500 points.

R-4B (アー4ビー)
This not-quite-so-heavily-armoured yellow airship is the boss for the fourth round; it will come down on Yūichirō and Sunday from above, then move to the left, then to the down-right, then up, then to the left again, then down, then right before repeating its pattern, and attacks by firing lasers from its nine front-mounted cannons at you. Once you've fired enough shots at all nine of those cannons to destroy them (for 500 extra points apiece), you will have to aim for its double-sided core (which is worth 8000 points and can be hit from the front with any type of shot, but can only be hit from behind if you had managed to win the After shot from Dream Co., Ltd. beforehand) - and once you have fired enough shots at that aforementioned double-sided core to destroy it the "stage clear" theme will be heard from the Yamaha YM-2151 for a fourth time as it explodes and sinks to the bottom of the ocean. It also reappears on the sixth round, but will come up on Yūichirō and Sunday from below and follow a different moving pattern.

Pyonpyon (ピョンピョン)
These jumping robots appear on the fifth and seventh rounds, and attack by jumping into the air in order to come down on Yūichirō and Sunday from above; Dr. Kubota's powerful "dog-like" machine can also spit them out of its mouth (they can also spit projectiles at that point). 500 points.

Ja (ジャー)
These large jar-like robots appear on the fifth round and attack by flying towards Yūichirō and Sunday while firing projectiles at them; 500 points.

Muteppo (ムテッポー)
These smaller jar-like robots appear on the fifth and seventh rounds and will attack by firing three projectiles at Yūichirō and Sunday; 500 points.

Crystal Head (クリスタルヘッド)
This crystallized dragon's head is the boss for the fifth round; he is the only boss in the game who does not possess the ability to move, but will open his mouth to spit amoebas at Yūichirō and Sunday (which come in two different colours: red and blue - and, if you can fire enough shots at them, you can destroy them for 100 extra points apiece). Once you have fired enough shots at his top half to defeat him (he is worth 10000 points), the "stage clear" theme will be heard from the Yamaha YM-2151 for a fifth time as any amoebas that are currently on the screen explode and leave 100 Crystals behind, and that top half propels itself into the air and explodes releasing hundreds of crystals; you should try to collect as many of them as you can before they all float away. You can also see in that image to the left that you'll have to contend with three Ao Tanks during this battle - so it is advisable for one of you to choose the Stock bomber shot from Miyuki Chan's Kūchū IN here if you had not won it from Dream Co., Ltd. beforehand.

Perikan (ペリカン)
These pelican-like robots appear on the sixth and seventh rounds and attack by rearing up, opening their fronts, and firing homing missiles (worth 50 points) at Yūichirō and Sunday; they are worth 1500 points, and when one of them is killed, he will leave several Crystals behind.

Maiku (マイク)
This microphone-like robot is the fourth and final boss of the sixth round; he's protected by a spinning barrier of forty balls which are similar to those in Power Station's rotary mechanism, and they must all be destroyed (for 500 points apiece) before Yūichirō and Sunday will have a clear shot at him. He will attack by firing missiles at them as they are doing this, and once they have all been destroyed, he will start ricocheting around the screen while firing lasers at them from all directions - and once they have fired enough shots at him to defeat him, that "stage clear" theme will be heard from that Yamaha YM-2151 for the sixth and penultimate time as he explodes into twenty pieces of debris (which will not kill Yūichirō and Sunday if they fly into them, and will just fly past them). He is worth 10000 points, and is also the only boss in this game who does not have a theme of his own; as with the reappearances of Fire Tortoise, Power Station, and R-4B at earlier points in the round, Kuchu Yosai's theme is reused.

K-Blocks (K-ブロックス)
These turquoise blocks appear on the seventh round, and attack by moving either vertically or horizontally; they cannot be killed, only avoided.

Nokogiri (鋸)
These saw blades appear on the seventh round, and attack by moving vertically; like the K-Blocks, they cannot be killed, and must be avoided.

Nuts (ナットス)
These mushroom-shaped hardware fasteners appear on the seventh round and attack by moving either vertically or horizontally while spinning anticlockwise; like the K-Blocks and Nokogiri, they cannot be killed, and must be avoided. They're also the last regular enemy you'll encounter.

Dr. Kubota (Dr. クボタ)
The "main" antagonist of the game; he has kidnapped Kana Aihara, so as to get Yūichirō and Sunday out to rescue her. At the end of that seventh round, he appears as the game's final boss in a powerful dog-like machine that will first roll into view from the right side of the screen, then spit three Pyonpyon out of its mouth (which can be killed for 500 extra points apiece), then jump up into the air three times before somersaulting back over to the right side of the screen. He will now somersault up to the top of the screen and spit seven homing missiles out of his machine's mouth (which can be destroyed for 50 extra points apiece), then somersault down to the left side of the screen before somersaulting back to the right side of the screen and spitting seven more homing missiles from his machine mouth at you - and he will then spit three more Pyonpyon out of his machine's mouth and somersault over to that left side of the screen, before jumping up into the air four more times and repeating his pattern. Once you have fired off enough shots at the machine cockpit to defeat him (he's worth 30000 points), the "stage clear" theme will be heard from the Yamaha YM-2151 for a final time as it explodes; he will then ascend to heaven as an angel as Kana Aihara appears in the bottom-right corner of the screen. Both players will then receive 20000 bonus points for every life they have remaining and the amount of Crystals they have remaining will also be added to their scores - and both Yūichirō and Sunday will now fly down to Kana in slow-motion as the screen fades out.
