Great work! I really like the idea and your selfmade physics. The drifting is cool, too.
IMO the camera sometimes comes too close what makes me dizzy, but that's just a matter of taste, of course. Please add online multiplayer, as I currently have no one else around, too. Usually, I prefer local gaming over online gaming, but it can be funny with Teamspeak, too.
Btw KarBoom is a nice title!
