Bubble Bobble

The gameplay involves a platform game with each level being a single screen. The player must clear enemies from a level to progress to the next one. With one player controlling Bub and the other controlling Bob, the player can jump, collect items for points (such as fruit), and use the ability to blow bubbles. Bubbles can be used as platforms or to trap enemies, which must then be popped by jumping into them to turn them into fruit. Power-ups may also be trapped in bubbles, including lightning that flies out horizontally at enemies and water that drags the player and enemies straight down.
