EndlessEx

EndlessEx is a casual jumping and flying mini-game in which you tap W in a continuous rhythm to keep moving. The entire game takes place on one screen, with no levels or upgrades, and you can switch backgrounds without affecting your progress.

Keep going

Collect batteries to maintain your energy. The game ends if the energy bar runs out or you hit an exclamation mark. You earn one point for successfully crossing between exclamation points, whether or not you collect an energy battery, and there is no maximum score.
