Hah, this game reminds me of Reckless Drivin, an old Mac shareware game!
Being able to race against ghosts is a nice touch!
I like the rotating camera, but I think some of the floor textures could perhaps be simplified a bit. When rotated, some of the textures produce a moiré pattern at this resolution. Levels that use mostly solid colors don’t have this issue (e.g. rainbow road). Or, perhaps you could keep the textures and always draw them “upright” regardless of the camera’s rotation? No idea if this would look good, just throwing ideas out there :)
Great job designing so many tracks as well! A very complete entry.
