It's strange that gravity and hopping is upside down so it's more like a Ceiling Floppy Cube xD
Anyway I really liked that difficulty ramp as you go, I've reached 58... what's your best highscore? ;)
Wow! 58?! My highest was 46!
Thanks for playing the game mate! Because in Processing the positive direction for y axis is downward, thus the inverted gravity so I can save a few characters writing the code XD.
