Move: Press left/right arrow keys or A/D Jump: Press up arrow key, W, or L Run: Hold Z or K while moving The longer you press the jump key, the higher you will jump. You can go even higher by jumping while running. Collect coins to earn points. Jump on enemies to defeat them. Don't get hit by them, or you will die! Some of the enemies jump, so be careful! If you fall into the void, get hit by an enemy, get crushed, or run out of time, you will die.
