I think that all tramp sims should be like this one. Arrow keys to move. Up and down arrow keys will slow/speed up your ball when going up/down. Update: Before you couldn't tell that the ball had three costums, But i just made it so that if its going slow enough it will not go all the way flat. Update2: Made it a bit more realistic. (Bounce by the edge to see what i mean. Hope you like it if you do please press the love it button.
