Captain ED

Captain ED (キャプテン えど) is a Adventure/Shoot 'Em Up video game published by CBS Sony Group, Graphic Research released on 1989 for the NES.

The player controls a ship armed with a blaster and a large mallet; they must navigate through "space" - an environment vaguely resembling a disco floor - while avoiding various other spaceships (or preferably destroying them to earn money!). Destroying enemies with the mallet is risky but nets a money bonus. In addition, the player's gas (life) ticks down constantly. It is also reduced by damage from enemies. To counter-act this slow grind to the death, the player must buy more gas. This results in cyclic game play; destroy more enemies to buy more gas. In addition, the color-changing floor has various effects on the ship: On green tiles, gas consumption is at the normal rate, on yellow tiles it is slightly increased. Red tiles rapidly deplete gas and violently shift the spaceship; this can result in difficult situations where the ship is forcibly moved from one red tile to another repeatedly. Blue tiles, only revealed by the pickup of a smiley face, very slightly increase the player's gas, but at such a slow rate it is almost unnoticeable.
