Second Mugger Level
...How? I was playing and actually enjoying the game up until this point. The brakes do NOTHING as far as I can tell. I know I have them equipped, because I can see myself slow down when I press spacebar. However, they do not help with the one-way arrows at all. I went around that circuit about three dozen times without ever once coming close to making it in that tiny hole; with how bouncy the physics are, getting into a hole that small would be tricky ~without~ the one-ways. Arg.
Perhaps make it so that the brakes completely negate one-ways? That would play heck with your level design I'm sure, but it would make them a more useful powerup, and make that level a lot less frustrating.
Anyway, I'm sorry I can't make it through, because I was actually enjoying the game up 'till that point... Ah, well. You get a 7; not the best game I've ever played, but far from the worst.
