Starts off as an easy to learn, hard to master kind of game with how it controls, taking you through a bunch of cool looking levels that ramps up the difficulty reasonably well. Then you get to the final 20 levels and that curve turns into many peaks with few valleys. That said, I'd be lying if I said I didn't have a good time with those last few levels, albeit in a masochistic way. I needed to grow more hair on my chest, anyways.
