It was pretty fun; great job! It was annoying how there were extremely visible seams on the terrain but that's a pretty minor thing.
The more concerning thing was how I kept getting stuck on the sidewalls. Any time I brushed up against the sides I got stuck. Usually I would also end up turned around, which is worse than if bumping against the walls stopped me outright. And getting stuck happened the most when I used a turbo; far from helping me, using a turbo often put me further behind because I would get stuck against a wall and everyone would pass me.
You might want to look into that, maybe having the player bounce off walls or something.
