An option to somehow lower your speed stat would be nice. I got mine pretty high to get the one achievement, but now I move to fast that I overshoot the shop every time.
Fun game! Some kind of timer stating how long it takes to beat a level would be nice, so I know how close I am to getting that "beat a level in 15 seconds" achievement. :)
