It looks really slick and the drifting is fun but I found the "turn-based with realtime ticks" a little jarring as the movement kept stopping and starting. I think it could be interesting to experiment with changing the animation style to be smoother, and may introduce a fully turn based mode. Also I'm not sure if it was just running slow on my machine of if it was running at the intended speed. Might be useful to let the player choose the game speed.
Also it seems to freeze after I die and I need to refresh the page each time.
