WOW these turn physics feel fantastic once you get a hand of the controls (Turning relative to your car without camera motion can be very tricky, but the lack of camera movement did make it a lot easier to learn the map layout, in fairness), that said, it was kind of annoying needing to slowly back out of a wall when I inevitably crashed - perhaps the car could slide along the wall a little while moving forward (Looking at the car physics you sourced, I think this could be done with some adjustments to slope physics). Obviously this can do with some more visuals & sound design, just a couple additions from some premade asset packs or royalty free artists would go a long way - but I think my main suggestion would be some quality of life tweaks - perhaps a lap counter, minimap, per-lap timer, or maybe some indicator for how I'm getting points? All that said, this is a first game, and I'm impressed you took on a game jam for a first released project. Good work, please keep making things.
