The Return of Ishtar/Gameplay

Controls

 * Joystick: Use the 8-way joystick to direct Ki (or Gil if you're player 2) around each room. (The screen will only scroll according to Ki's location). While holding down the second button, Ki can use her joystick to cycle through the six different types of magic spells ("ATTACK", "PROTECT", "ASSIST", "LIGHT", "MEDICAL" and "SPECIAL") and select them with first button.
 * First Button: Use this button to make Ki cast her currently-selected spell at the enemies. (Gil will automatically draw his sword whenever an enemy gets close enough to him). While holding down the second button, Ki can use this button to select a different spell. There are a total of sixty-four different spells in the game - but she will only start out with ten of them.
 * Second Button: Use this button to make the menu of spells appear in the bottom-left corner of the screen. As mentioned in the section on the joystick above, Ki can cycle through the six different types of spells with her joystick, and select them with first button, but she will lose the ability to move and cast her currently-selected spell at the enemies while doing so.

Ki and Gil
The two protagonists of the game; player 1 controls the spell-casting Princess Ki (shown in the image to the left), while player 2 controls the sword-wielding Prince Gilgamesh (shown in the image to the right). The screen will only scroll according to Ki's location - so if you are player 2, you will have to stay close to your partner if you want to explore the rooms. Ki will attack by casting spells at the enemies, while Gil automatically draws his sword whenever an enemy gets close enough to him; however, each time Gil kills an enemy with his sword, the numerator of the fraction in the bottom-right corner of the screen (the denominator starts at 15) will decrease by a preset amount depending on what enemy type it was. If it goes down to 0, he will evaporate, and it is game over for both players - and it is also game over for both players if Ki is touched by any enemy at all, which instantly makes her evaporate.

Vampires
These blood-sucking monsters come in four different colours - purple, orange, green and black. The purple ones take two hits to kill, the orange ones take four hits to kill, the green ones take ten hits to kill, and the black ones take twenty hits to kill. None of the four varieties of Vampires have any recovery points.

Slimes
These oozing blobs come in eight different colours - green, black, red, blue, yellow, pink, dark yellow, and dark green. The green ones will take 6 hits to kill, the black ones take 10 hits to kill, the red ones take 34 hits to kill, the blue ones take 56 hits to kill, the yellow ones take 106 hits to kill, the pink ones take 136 hits to kill, the dark yellow ones take 168 hits to kill, and the dark green ones take 208 hits to kill.

The purple ones don't have any recovery points, but the orange ones do have one recovery point, the blue ones have five recovery points, and the black ones have twenty recovery points.

The green ones don't have any recovery points, but the blue ones have 6 recovery points, the orange ones have 19 recovery points, and the black ones have 32 recovery points. The black ones are also known as "Otapyon" (Katakana: オタピョン) - literally how spelled in Romanji, unlike "Hanburabi".

Oozes
These smaller versions of the Slimes come in eight different colours - green, black, red, blue, yellow, pink, dark yellow, and dark green. The green ones take 18 hits to kill, the black ones take 96 hits to kill, the red ones take 296 hits to kill, the blue ones take 462 hits to kill, the yellow ones take 560 hits to kill, the pink ones take 666 hits to kill, the dark yellow ones take 842 hits to kill, and the dark green ones take 1039 hits to kill.

They may be smaller than the aforementioned Slimes, but they are certainly tougher...

Magicians
These warlocks come in four different classes - Mages, Druids, Sorcerers and Wizards. All four classes will take five hits to kill and have no recovery points.

Hyper Magicians
These "hyper" warlocks (which are identical in appearance to the regular ones) also come in four classes - Hyper Mages, Hyper Druids, Hyper Sorcerers and Hyper Wizards. As with the regular ones, all four classes take five hits to kill, and have no recovery points, but they materialize at faster rate than regular ones.

Ropers
These many-tentacle mounds come in five different colours - orange with green tentacles, green with red tentacles, yellow with blue tentacles, blue with yellow tentacles, and white with pink tentacles.

None of them have any recovery points, but the "pink" ones also have an "AC" after their colour.

Super Ropers
These "super" many-tentacle mounds (which, like the Hyper Magicians, are identical in appearance to the regular ones) only come in three different colours - orange with green tentacles, green with red tentacles, and yellow with blue tentacles. The "green" ones take 780 hits to kill, the "red" ones take 926 hits to kill, and the "blue" ones take 1026 hits to kill. As with the regular ones, none of them have any recovery points, but they move at a slightly faster speed than the regular ones (and also take more hits to kill).

Knights
These armoured warriors come in total eighteen different classes (a lot) - Blue, Blue Captain, Black, Blue Eye, Black Captain, Mirror, Golden Mirror, Hyper, Steel Hyper, Silver Hyper, Golden Hyper, Green Lizardman, Pink Sword (L?), Black Lizardman, Brown Lizardman, Red, Blue Shield, and Akynd.

As with the Slimes (but not the Oozes), they're also from the original game.

Will O' Wisps and Land Urchins
Will O' Wisps (shown in the images to the left) come in two different colours (red and blue), but Land Urchins (shown in the image to the right) only come in one (green). If Ki and Gil spend too long in any room after the song they are hearing from the Yamaha YM-2151 has increased in tempo, four Will O' Wisps will appear in the centre of the room and make their way to the corners before homing in on the heroes' current position; it is not known how many hits they take to kill or how many recovery points they have, but your best way of escaping is to collect the nearest key and head for the door that it opens. Land Urchins, however, will appear in both the third-last and second-last rooms of the game under the trap doors that you have to fall down if you step on them - and as with the Will O' Wisps, it is not known how many hits they take to kill, or how many recovery points they have.

Keys
In every room of the tower, you will come across at least one of these small yellow keys lying on the floor as you walk around; each one unlocks a specific door in the room, and once the player who has collected a specific key walks up to the door it unlocks, it will open up for them. Once both players have walked through the open door together (neither player can walk through an open door individually like in Namco's own Toy Pop), the name of the room it leads to will be shown on the screen and you will be given a three-character "Room Pass".

Treasure Chests
In some rooms of the tower, you will come across one of these small brown chests in a "hole" in one of the walls as you walk around; if Ki pushes the second button to bring up the menu of spells in the bottom-left of the screen and uses her joystick to select the Blue Crystal Rod spell, then uses it on the chest while facing it, it will disappear and its effects will be transferred to her until she and Gil leave the room. Some of them will even give her new spells, which will be displayed in the bottom-left menu of spells under their respective types.

Fork
This piece of cutlery appears in the Kitchen, and can only be collected by Gil, as Ki will just walk through it; it will give him the power to deflect the Magicians' spells with his sword.

"PROTECT"

 * Shield: Ki will always have this "PROTECT" spell when she starts the game. Its effect will increase the numerator of Gil's energy fraction in the bottom-right corner of the screen by one, and cause the preset amount that it decreases by whenever he kills an enemy with his sword (as mentioned above, it will depend upon what type of enemy it was), to go down by half.
 * Protection: Ki will also always have this "PROTECT" spell when she starts the game. It will generate barrier around her that renders her invulnerable until she and Gil leave the room.
 * Neutralize Spell I: This is the first "PROTECT" spell in the game that will be found when Ki uses the Blue Crystal Rod spell on a Treasure Chest, and will later be superseded by the "Neutralize Spell II". Its effect will give Gil the power to neutralize the spells that cast at him by the Magicians (because after collecting the Fork, he can only block them from the front).
 * Reflect Spell I: This is the second "PROTECT" spell in the game that will be found when Ki uses the Blue Crystal Rod spell on Treasure Chest, and will later be superseded by the "Reflect Spell II". Its effect will give Gil the power to deflect the Magicians' spells with his sword diagonally (after collecting the Fork, he can only deflect them horizontally or vertically).
 * Shield Redline: This is the third "PROTECT" spell in the game, that will be found when Ki uses the Blue Crystal Rod spell on a Treasure Chest, and will later be superseded by the "Shield Blueline" spell. Its effect will increase the numerator of Gil's energy fraction in the bottom-right corner of the screen by two, and cause the preset amount that it decreases by whenever he kills an enemy with his sword to go down by a third, which adds up to a total of a fifth - however, as mentioned above, it will still depend upon what type of enemy it was.
 * Protection Large: This is the fourth "PROTECT" spell in the game, that will be found when Ki uses the Blue Crystal Rod spell on a Treasure Chest, and supersedes the "Protection" spell that she started out with. It will generate a larger barrier around her that again renders her invulnerable until she and Gil leave the room, and can kill enemies by touching them.
 * Neutralize Spell II: This is the fifth "PROTECT" spell in the game that will be found when Ki uses the Blue Crystal Rod spell on Treasure Chest, and supersedes the "Neutralize Spell I". Its effect will give Gil the power to neutralize the spells that cast at him by the Hyper Magicians (because, once again, after collecting the Fork, he can only block them from the front).
 * Reflect Spell II: This is the sixth "PROTECT" spell in the game, that will be found when Ki uses the Blue Crystal Rod spell on a Treasure Chest, and supersedes the "Reflect Spell I". Its effect will give Gil the power to deflect the Hyper Magicians' spells with his sword diagonally (once again, after collecting the Fork, he can only deflect them horizontally or vertically).
 * Shield Blueline: This is the seventh "PROTECT" spell in the game, that will be found when Ki uses Blue Crystal Rod spell on a Treasure Chest, and supersedes the "Shield Redline". Its effects will increase the numerator of Gil's energy fraction in the bottom-right corner of the screen by three, and cause that preset amount that it decreases by whenever he kills an enemy with his sword to go down by a quarter, which adds up to a total of an eighth (counting other two) - however, as mentioned above, it still depends on what type of enemy it was.
 * Sword Barrier: This is the eighth "PROTECT" spell in the game, that will be found when Ki uses the Blue Crystal Rod spell on a Treasure Chest. Its effect will create a barrier around her that will render her invulnerable to the swords of all eighteen classes of Knights (or however many may be present in the current room) until she and Gil decide to leave that room.
 * High Speed: This is the ninth and final "PROTECT" spell in the game that will be found when Ki uses the Blue Crystal Rod spell on a Treasure Chest. Its effect will give Gil the power to attack the spells of the Druid and Wizard classes of Hyper Magicians (along with the Druid and Wizard classes of regular Magicians), before the aforementioned Magicians disappear.

"ASSIST"

 * Sleep: Ki will always have this "ASSIST" spell when she starts the game. Its effect will cause all eight varieties of Slimes and all eight varieties of Oozes to stop moving for a short time.
 * Rock Hold I: This is the first "ASSIST" spell in the game that will be found when Ki uses the Blue Crystal Rod spell on a Treasure Chest, and will later be superseded by "Rock Hold II". Its effect will cause all four varieties of Vampires, and all eight varieties of Slimes, to become statues for a short period of time, and you can safely touch them while they cast in stone.
 * Silence: This is the second "ASSIST" spell in the game that will be found when Ki uses the Blue Crystal Rod spell on a Treasure Chest. Its effect will cause the Mage class of regular Magicians to stop casting their own spells at Gil, for a short period of time - however, the Druid, Sorcerer, and Wizard classes of regular Magicians will still be able to cast their spells.
 * Smoke Screen: This is the third "ASSIST" spell in the game, that will be found when Ki uses the Blue Crystal Rod spell on a Treasure Chest, and shares its name with the Blue Car's method of stunning the Red Cars from Namco's own Rally-X and its sequel, New Rally-X. Its effect will temporarily disorient any members of the Blue class of Knights that walk into it.
 * Rock Hold II: This is the fourth "ASSIST" spell in the game that will be found when Ki uses the Blue Crystal Rod spell on a Treasure Chest, and supersedes "Rock Hold I". Its effect will cause all four varieties of Vampires, all eight varieties of Slimes, and the Blue class of Knights, to become statues for a while, and you can again safely touch them while cast in stone.
 * Panic: This is the fifth "ASSIST" spell in the game that will be found when Ki uses the Blue Crystal Rod spell on a Treasure Chest. Its effect will disorient all enemies in the room for a short period of time except for the four classes of regular Magicians, the four classes of Hyper Magicians and the two varieties of Will O' Wisps - so you will still have to deal with them.
 * Rock to Mud: This is the sixth "ASSIST" spell in the game that will be found when Ki uses the Blue Crystal Rod spell on Treasure Chest. Its effect will cause any Vampires, Slimes or Blue Knights that have been transformed into statues as a result of using the "Rock Hold I" or "Rock Hold II" spells, to disintegrate into puddles of mud (which will kill them instantly).
 * Wizard Lock: This is the seventh and final "ASSIST" spell in the game, that will be found when Ki uses the Blue Crystal Rod spell upon a Treasure Chest. Its effect will cause all four classes of regular Magicians and all four classes of Hyper Magicians to stop casting spells at Gil for a short period of time (despite its name, which implies it only works on Wizards).
