left and right arrow to move press x to erase what you draw press r to reset ball for now just play around, report any major bugs I know it doesn't work when you try to squeeze the ball through something, just like don't do that. Also to be honestly i'm kinda confused how normal force works, if someone would help explain, because what I currently have kinda makes no sense. also currently only really works the intended way on convex shapes... will try to figure out concave ones later... if you at all want to use please credit @sppurpleeagle02
