The game looks great and got super interesting when I figured out how to use the hat abilities. It unfortunately crashed as I was going up the right side wall on level 2, but there's definitely that start of something fun here.

Is it possible that you tried to open the hat menu on the floating fire platform? It is a known bug that the moving platform interacts with the physics engine in a weird way when opening the hat menu while standing on it. This causes you to shoot up about 4 million pixels and causes the camera to lose track which in turn makes the game unplayable until you restart.
