The mechanic with scaling your car to either be fast or have better turn speed was a really creative and fun idea - We liked that it had significant impact instead of minor number changes! It changed how we played the game, and we liked it!
If we were to pick an area of improvement, the collision handling with the other vehicles could use some tuning.
The art was good, and we especially enjoyed all the UI graphics - Very cool, very stylish, very chic. 10/10.
Well done!
