What worked:
It has a cool aesthetic going for it. The sound for the next fuel is a nice touch to help you know the general area to go to. Crashing looks cool with the car exploding and sometimes flipping over. Drifting works well.
What didn't:
It is very hard to tell what is a wall or not since it all becomes white. The level design feels too claustrophobic with the stipulation of not being able to slow down. I want to speed around with that rule in place, but the level forces me to make very sharp turns at every second and manage my speed. There was no quick restart or menu option that popped up on death, which was frequent enough to make it annoying having to open up the menu every time (except when setting a record).
Bugs:
The optimal way to play for the highest score is to never start moving or to never pick up the first fuel blip, since the timer starts as soon as the game does instead of when you start moving, and the mechanics (can't slow down, fuel) never start until you pick up the first fuel blip. The mechanics not starting until you pick up the first fuel blip is nice so you can explore the map and test out driving, but the timer should also start with the fuel blip in that case.
Great job!
