The controls are quite weird to play but I think it's fun. I got to about 300m but I think it's odd that there's no reverse option since it's quite easy to get stuck on the edges so I had to reset a lot (which also made me lose a lot of time).
Thanks for the feedback! There is a reverse option. Using "S" (or the brake "E") will reverse. I probably should have documented that in the controls section.
