This is a really great game, and I love the addition of different stats with different cars, it adds replay value since most of the fun and challenge comes from the learning curve in mastering control
Edit: I've found a bug, well really an exploit. When you pause, you lose all momentum and have the ability to control which way your car will face when you unpause. For instance, if I were careening towards an edge head-on I could just pause, hit right twice, and unpause to instantly start driving in the opposite direction with no consequence. Also it seems that other cars still move while you're paused, so they can still hit you
Edit 2: There's another bug where if you go out of bounds right after crossing the finish line of a level, the game will lock you in a loop of crashing out of bounds next time you go back to that level. Refreshing the page will fix this, though
