Biest, Trust me it's the game. I've seen it crash on several different PC's. I could understand my laptop or my friends desktop, but even mine desktop too.
Besides the Slight lag at times, which completely breaks this game, ignore the poorly chosen words of the negative comments. This is a great game and if you have any knowledge of Flash this is very difficult to pull off.
Thought the controls need to be a bit more tight this game needs MP, create your own course, and when you level up you need to control your own stats. Stats were the most frustrating because I just wanted to go much faster, screw my handling!
