The driving feels really good, nice drifting. I like the nitro mini-game, though it's hard to look at the road while playing it. The bright yellow and blacks work nicely together. I can see everything clearly even at these speeds. Looks nice too.
Respawn was essential. A reverse button would have been great in its place a lot of times. I just needed a little backing up to be on my way.
I fell through the world a few times only to find another city beneath me. I feel like you took a bug and turned it into a feature there. It was pretty cool anyway. Another loop.
Fun arcade-y game.
