Oh no, I drove the car off the map, and now it's gone. Then, I managed to get the car back on the screen, but it disappeared again, and I couldn't find it. As a demo, the racing game is very functional in showcasing player-based control for the car. However, the car is easy to make disappear if it's driven off the racing track. Excellent choice of music!

The "game feel" is greatly enhanced by increasing the frame rate. (Why did you pick 20?)

I found good results increasing the frame rate to 30 fps.
I also tried 60 fps, but then it is necessary to lower the car's max speed to compensate for this. (Even better would be frame rate independent movement, but that is beyond the scope of this comment.)

Another user mentioned collision. AS2 has a method for point-shape collision, so I think the best bet would be to check for each of the 4 corners against both of the grass shapes.

This has potential! I think the map should be a bit bigger. Maybe add a camera? The math can be a bit confusing (doing it from scratch) if you haven't done it before, but I think there are VCam scripts that make it easy.

The driving mechanics are functional, but the lack of collision obviously makes it impossible to have win/lose conditions or even a complete game loop. You could probably add a speed penalty for going off-course in about 10 lines of code and counting laps or completion time wouldn't take much more than that and would actually give the player an objective to shoot for.

Bruh

broke the game but still funny xD
