weird
The idea is great but you gotta work on your game physics, man it really confused me when the marble started hopping around when it got to the walls and when it would sometimes stop one distance from the floor and then it would stop higher.. when you code the walls/floors, make sure to make it so the marble behaves the same no matter which side of the wall/floor it hits (bounces) that way, there wont be any more of this weird twitching. Another thing I noticed is the fact that the marble can move THROUGH the walls if you keep the right arrow pressed. Aside from these minor mishaps the game was pretty cool make another!
