I appreciate the sound design. You made do with what you had but it gets very grating after a while. Some kind of randomization or pitch shifting would go a long way to improve the listenability of the game.
Overall, the game controls well I would say. The way the trees approach is rather strange but accurate to the original game. My biggest complaint about the movement of the game is the turning. It feel like the turning is very slow and doesn't give me the feeling of turning around in an open space but instead it seems more like I can only swerve left and right on an endless track.
