Thanks for the feedback and suggestions! I especially appreciate your reminder to avoid burnout, I wish this was much more common here on Itch :--)
Clockwise tracks would be cool, if only I were to at all refactor my track generation code (it's hardcoded and very poorly written). The starting positions already randomize, evening out the advantage of the inside line. I'm also making car to car collisions a bit different next, which might affect this too as blocking/pushing the other car will be easier. Let's see!
The way I've added replay value in my games in the past is by adding per round random modifiers. This is something I personally really enjoy in casual local multiplayer games and it's also a lot easier to add to the game, and it balances skill differences the players may have. This is the way I'll probably add most features to this game too, but I'm not ruling anything out :---) Thanks for the suggestions, they're really fine!
