Tropical Grand Prix: you against four AI drivers, three laps, item boxes, a live HUD and a minimap. Hold space through a corner to drift and fill the boost meter, bank it, then spend it on the straight.
It started as a single-file prototype and grew into a proper modular build once the handling felt right. The prototype is still in the repo as the behavioral reference, which is the way I like to work: get the feel first, then make it maintainable.
