One or two players try to collect items as they move along, jumping over or shooting enemies. When an enemy has been shot, it will encase him in a bubble. You must jump on the bubble to pop the enemy before he can get back out.
This game is very similar in play to Super Mario Bros.. There is a time limit to complete each level, you must jump up to break blocks and, in two-player mode, players must progress at the same time. If one stands still the other can only move a few steps before the screen will not scroll any farther.
