The turning on both of the starter cars feel way too slow, I feel the controls should be way more fluid for a game like this. It's impossible to make tight turns with the blue car to grab coins or bait cop cars into crashing with how much it slows down whenever you turn.
The polish was nice. I particularly liked the explosions, though I think the cars could use more polish (like dust trails. tire tracks, or fire coming out of the exhaust pipes when going really fast)
