I would have expected to heal while you're on the ground, because like this you're basically just trying to kill yourself to reach the highest score.

It is a fun game and cool concept, but I found it hard to figure out what to do at first. There is also a bug/exploit you can do by pressing "x" as when you restart you get slightly airborne.

This is really impressive to put together given the time - and after a bit of playing I got the hang of the scoring.
At the start I was unsure how to do tricks or find the pickups, and often got the car stuck (e.g. on rails). Glad to hear you'll be working further on this!
It would be great if you were able to rate and review our submission too - thanks!
