To move use arrow keys, wasd keys, or your mouse or finger to move. There are 6 levels. Touch the circle in the top right corner to get to the next level but before you can go to the next level you have to collect the coin. If you are touching the trampoline (the green thing) and jump you will jump extra high. Don't touch the red stuff. It is dangerous and will set you back to the beginning of the level. Customize the volume using the volume variable.
I'm still working on it. If you die and the coin doesn't reset and show if you already collected it then just die again and it will respawn.
