Maddeningly simple game: Rebound MAY 14 2013
Two controls, one bouncing stick, uneven terrain that eventually falls out from under you, get the stick as far to the right as you can. Harder than it sounds. I got 107.04 on, like, my 2,341st try. (Cheat code: you can get pretty far just by holding 'A' down.) Also fun: seeing how far to the left you can get...I couldn't get much past -48.
