The instructions are in the game but here they are! Clap or yell "Jump!" (or press the space key) to make the ball jump. Survive for as long as you can! It might take a while to get used to it and at some point, they come too fast for you to jump over all of them, but good luck!
Inspired by @speakvisually to use sound to control the ball. I used GarageBand to make the ending. ver.1.0 Shared!
