I liked the visuals of this game. The world felt like it had attention paid to it, as there were recognizably different neighborhoods with different styles to them.
At first, the world did feel too large, and the delivers a bit too long. Then I remembered there was an upgrade ability and reread the instructions. It also took me some time to realize the boost worked as a slow build-up. I was expecting more immediate feedback.
Nice job on this submission!
