It's actually not a bad game, and provides a quick distraction. Each level gets progressively harder, which is as it should be. Music was annoying after a while, but you did include a mute button for it, so that's a big plus. The graphics were pretty good. However, it just didn't have any real "physics" feeling to it. For example, it didn't matter how fast the hedgehog was traveling down a hill, it would still go in the hole instead of pass right over or bounce out. Still, it was a decent game.
