I managed to beat it! I absolutely love the idea, and the controls feel amazing most of the time. It felt so good to quickly slow down the vehicle for a precise turn, and then speed them back up to race to the oxygen tank. There were quite a few moments where I tried to turn left and died because of it. It feels so natural to be able to move in all four directions, but I understand that's just part of the difficulty of this game. Great work!
