This is Loose Gravel! A pseudo-3d racer that started as a proof of concept, and gradually grew into something of a game.
If you're curious, you can view the progress here.
Pretty self explanatory. Choose a course and try to overtake the other cars in 3 laps to win.
Courses are randomly generated but have their own unique parameters and feel.
I was planning to add a tournament mode (and some more tracks), but I ran out of cart space (so that means it's finished! :) )
Tip: If you tap the up arrow you will keep accelerating until you hit something or drive off the road. You don't need to hold it down.
Enjoy.

Update: Replace scaled map routine with tline version
