This looks great. I also really liked the test video of gameplay!
It actually has a track editor ans several different blocks, that thing in the middle represents one of them, of course, something you need to avoid to go faster.

Thats a test of the alpha of the game done by someone we don´t kniow, most of the graphics have changed and a lot of the game loop and UI too since that, but you can get an idea of how it works.
Hills and a curvy race track, looks like a racer's dream. By the way, is that an apex in the middle of the road? O.o
Well thank you!
