Really enjoyed playing Rush hour its got a simple but effective gameplay loop and I had to actually stop myself from playing more! thought the hitboxes for the cars seem a bit large, making them smaller would allow for a lot more near misses which will make the player feel great even though technically they should have hit the car, but that can be our little secret. I feel like if you make that change and maybe polish the game up a bit more you could totally put this on an app store.
