Overall I enjoyed the game. Just the steering feels a little stiff.
The physics seem to be a little bugged. Some times at high speeds I have the feeling the car is passing through the platform, also sometimes the jump distance is not measured. The first time it happend I thought it was because I drove too far to the right, but the second time I aimed straight for the white circle. I guess I passed through the green surface and didn't get high enough to trigger the measurement.
