Fun game! Really enjoyed the low poly 3d aesthetic and the soundtrack was great. A few minor things that I think would make the game even better:
1) Echoing the sentiment that others mentioned about the road being a bit nauseating. I spent most of my time playing looking on the top half of the screen b/c of this
2) The AI controlled sportscar asset breaks the immersion of the low poly world you probably worked really hard to create. Even if you swapped those models out for blue-painted versions of the player's car, that'd work.
3) The procedurally generated track on Spaghetti Junction pathed straight through the end-of-level cube and it almost blocked the whole track. This is a bug that could really ruin someone's playthrough if the track became completely obstructed.
4) My car got flipped by one of the AI crashing into me and I couldn't get flipped rightside up to finish the level so I had to hard reset the game. Would be sweet if this could be fixed.
Sorry for the essay! Really fun game and the first level was super therapeutic, ha.
