Crap.
The point of this game is to get as far as possible to submit your highest score, but they've already been tampered with. My best can't even get over 200m, but scores are way over 800, one being over 1,000.
The graphics are alright, but everything else is lacking. No instructions, no way to keep bouncing or keep moving, it's just frantically throwing your mouse around and that's it.
