Thanks for the nice comment! I'm considering remaking the game and putting more work into it. I really don't like the unpredictable physics and the terrible track system. Maybe after some other minor projects.
The physics didn't seem too unpredictable. The only part that seemed a bit unreliable was the turn after the hill. I just went really slow most of the time to prevent an accident. If you end up remaking it, let me know!
