Up arrow to jump, left arrow to move left, right arrow to move right. Also, W is up, D is right, A is left. That's it. It's THAT simple. (R to restart, but I don't see why you would need to.) The object of the game is simply to touch the yellow, avoid the red. Of course, this simple task can be difficult, but don't give up!
i wish i made this on my own lol
