Use the arrow keys (or WASD) to move, and space to dash. Dashing gives you temporary invincibility. Oh, and avoid the green. There will occasionally be coins that will heal you if you get them. When you die, click the green flag twice.
The song used in this level is "The Race Around the World" by Waterflame. Sound design by me. Also, the whole concept of the game is taken from a far superior game named Just Shapes & Beats.
