Thanks for the detailed feedback! I think your read on the game is pretty fair.
The repetition and lack of environmental variety are definitely two of the biggest things I’d want to address in a larger version. More obstacle types, roadside props, scenery, and generally more things happening along the drive would help a lot.
The rough-route difficulty is interesting feedback too. I wanted those sections to feel noticeably more dangerous, but I can definitely see how the combination of dense obstacles and the car’s loose/slippery handling can push that too far.
Audio is another area I’ve heard pretty consistently needs more work. Music/ambience and more variation in the car sounds would go a long way.
I’m really glad the core risk/reward idea and theme landed for you, though. That was the main thing I wanted to prove with the jam build. Thanks for taking the time to write all this!
