Good, but seems unfinished
The controls were good, and I really liked the tyre marks. But other than that the game needed a lot more. The courses were extremely dull, Add more than just green ground/grey walls. I think you'd be better off having a 'beat the best times' system than this 'get as many laps as possible'. Maybe put in some hazards too like oil or glue. And speed ups. It could be good, just needs a bit more work.
