Bomb Jack/Gameplay

Controls

• Joystick: Use the joystick to control the movement of Jack. Press left or right to make Jack run in either direction, or to fall through the air in either direction. Hold down to make Jack fall back down to the bottom of the screen faster, or hold up to enable Jack to jump higher than usual, to the top of the screen.
• Jump: Press the jump button to make Jack jump. The longer the button is held down, the higher he will jump. Jack will jump even higher if you hold the joystick up while jumping. Once airborne, tap the jump button once to make Jack stop rising in air. Tap the jump button repeatedly to make him descend slowly to the ground.
• 1-2 Players: Press either button to begin a one or two player game.

Player

You control Jack throughout the game. Jack's one and only mission is to collect all of the bombs in the stage before moving on to the next and collecting more. In his way will be several enemies which will seek to stop him. Jack will lose one life any time he comes into contact with any of the enemies. There is no time limit, so Jack can take as long as he needs to clear the stage. However, the longer you wait, the more likely it is that the enemies will overwhelm him. Jack can turn the tables on his enemies by collecting a power coin, which will temporarily turn all of the enemies into coins which he can collect. Whether Jack earns extra lives by reaching certain point values is operator controlled in the arcades, and is usually turned off.

Bombs

Bombs are the focus of Jacks objective. In order to clear each stage, he must simply collect all 24 bombs that are scattered around the screen. However, once Jack touches the first bomb, the wick of one of the other 23 bombs around the stage will light up. Whenever a lit bomb is collected, another bomb lights up. From this point on, Jack can collect more points by focusing his efforts on the lit bombs. And Jack can earn a substantial stage completion bonus if he collects 20 or more lit bombs within a single stage. Unlit bombs are worth 100 points, and lit bombs, which stay lit indefinitely and never explode, are worth 200 points. At the end of the stage, if Jack collects 20 lit bombs, he will earn a 10,000 point bonus. If he collects 21 lit bombs, the bonus is 20,000 points. 22 lit bombs earns him a 30,000 point bonus, and if Jack manages to collect all 23 lit bombs, he will earn a whopping 50,000 point bonus.

Enemies

Enemy	Name	Description
	Bird (Badora in Japan)	Flies vertically or horizontally, but constantly seeks towards Jack. 1 will appear during the first 10 Rounds; after Round 10, 2 will appear. Movement speed increases throughout the game.
	Mummy (Nonon in Japan)	In early stages, they walk back and forth on platforms before falling over the edge; in later stages, they do not hesitate falling from the platform. Spawns in a light spark from the left or right side in the stage's top section where Jack is not currently located. Transforms into one of the 5 enemies upon landing on the ground floor. Sphere (Ball A) Bumps around mindlessly, trying to occupy the same vertical row as Jack. Floats up and down uncontrollably. UFO Changes velocity upon hitting something. Moves travel fast if they are far from Jack, and slow when they are close. Orb (Ball B) Slowly floats around, seeking Jack by occupying the same horizontal row as his. Floats left and right uncontrollably. Horn Bobs around the stage with no set intelligence. Caution: lack of attention to them holds a surprise despite their predictability. Club Seeks Jack just like Spheres and Orbs, but controls their motion in any direction.

Items

Item	Description
	Power Coin: A meter surrounds the bonus multiplier at the top of the screen. The meter has 20 segments; unlit bombs fill out one at a time while lit bombs fill out two at a time. When the meter is full, the power coin appears and begins to bounce around the stage. If Jack collects the coin, the enemies will turn in to coins temporarily. The color of the power coin changes whenever Jack jumps or touches a wall or ceiling. The color determines how many points the coin is worth when Jack collects it: BLUE = 100pts., RED = 200pts., PINK = 300pts., GREEN = 500pts., AQUA = 800pts., YELLOW = 1200pts., GRAY = 2000pts.
	Coins: Enemies will temporarily turn into coins whenever Jack collects the Power Coin. During this time, they remain frozen in place, and Jack can attempt to touch them in order to collect them. Collect them removes the enemy from play when it's time for the coins to return to normal. The coins will blink before they return to enemies. Each coin is worth an increasing number of points, starting with 100, and rising through 200, 300, 500, 800, 1200, and finally 2000. The number of points are also multiplied by the bonus multiplier.
	Bonus Coin: Bonus coins will appear every time the score reaches a multiple of 5,000, until the Bonus Multiplier at the top of the screen reaches ×5. Each time Jack collects one, he will earn 1000 points and the multiplier will increase by one. Each stage begins with a Bonus Multiplier of ×1, so only four Bonus Coins will ever appear per stage.
	Extra Coin: Extra coins appear whenever Jack has "killed" enough enemies by collecting them when they are coins. Collecting one will give Jack 3000 points, and one extra life.
	Special Coin: Appearances of these coins are extremely rare. If you manage to be lucky enough to catch one, you will earn 5000 point, one free game, and you will automatically advance to the next stage.
