WASD (or arrow keys... if you're one of THOSE people) to move and jump.  Get to the flag to prove your worth.  No double, or triple jump limitations in this game, jump infinitely and to  your hearts content.  

Gravity changes directions based on the color of the background.  Things may sound complicated, but generally, use the direction key for the direction you want to go.

3 modes to master: Original, Reverse, & Challenge.

Blue:  Normal downward gravity, about what you would expect.


Orange:  Gravity is  to the right.  Use Up/Down or W/S to move and A/Left to jump



Green:  Gravity is up.  Still use Left/Right or A/D to move, but jump is now S/Down



Red: Gravity is to the left.  Use Up/Down or W/S to move and D/Right to jump
