The sound is very well done and plays an important part in warning you about upcoming enemies, giving you a chance to respond before it's too late. The animation is very fluid, the voice-overs are professional, and the accompanying music is a pleasure to listen to. To increase replay value, there are a few other game modes that can be unlocked such as single player survival and local multi-player races.
Warning: This game is very difficult and is not for those with a short attention span. It takes a bit of time to learn the controls and proper timing to succeed.
