We must tell it: Go fullscreen and the game will lag, and it might costs you some lifes. (Btw, since we're unsure of what the remixes would be, we prefer to put a remix protector by @geocashing which tells if it's a good or bad remix or if it's a remix or not.)
The 'physics' of the characters are based on @JamesOuO 's Game Engine 1.0 character 'physics'. AF20Cartoons will, also, help us to do a future part of the game. We're sure it has a LOT of glitches that we didn't discovered yet, if then, tell us in comments. (Note: Some few glitches about the 'physics' are kept for some levels, so do not complain much about them.)
