Honestly, I don't know if this is just a me problem, but the game didn't work for me. The controls just weren't working I couldn't get past the first area.

Thanks for playing! The game is intentionally hard, so don't feel bad about not making it far ':)
In case the controls just weren't clear: The angle you draw controls the angle of the cap when you start jumping (as indicated by the character "rotating"). The distance you draw controls the strength of the jump (indicated by the line color). Wiggling the mouse while in the air makes you fall slower. It takes a while to master the controls, but is definitely possible :)
