A fun casual driving game. The car movement feels incredibly good in my opinion, and the procedural world generation is a cool idea (I personally haven't seen it ever before implemented in a racing game). Very nice game!
For me the timer felt a bit off, like I was just driving casually and suddenly the time runs out. I suggest there could be a setting to disable it. Other thing is that the places (biomes?) seemed to come always in the same order, I think it would be better if they came randomly. And finally, if you continue the development of the game further, it would be nice if there were some VFX and SFX just to bring that more polished feel.
But either way a very good experience, nice job!
