I found a bug that allows you to do a double jump.

Jump over a block that haves a clear down-right corner pressing "W+A" and without releasing and without releasing any key press "D" when you touch the wall. There's a moment where the chairwheel is under the block and the game allows you to jump in the air thinking that your're over that block.

Hi, the engine I used to make the game is pretty old, and when i was making the game i noticed this, so i tried to incorporate it into some the levels, thank you for telling me about the glitch on that level.

Have a great day!
