The racetracks are generally mazes composed of 2D square blocks whilst your vehicle is an icon in a bubble, controlled with the arrow keys (there is a distinct watery feeling to the background and the physics that makes control more tricky than a simple road-based game). Later levels introduce blocks with different properties such as sticky, spikey, bouncy, breakable and (most annoyingly) invisible. You can slow down the opposition by blocking or bumping them but for maximum satisfaction, bash them into the spiked walls. Occasionally, short cuts and alternative routes are available and this means a bit of solo practice can be time well spent.
