Nice game! It doesn't get boring with the rather funky car behaviour. Some things I'd add if I knew how to make games:
1. Coin counter, the lack of it makes a feeling of a lack of progression
2. Turn down the post-processing, it feels like the cars are made out of lightbulbs, jee.
3. More sounds and music would be nice, it feels very empty.
4. The visuals are pretty underwhelming. You drive in an empty void, on a brightly glowing block of cheese being chased by a block of very, very moldy cheese while collecting yellow dots, which are also brighter than an quasar. I'm not saying "go pay 99999999.99$ to guy on the internet to make you a car model with an atomic level of accuracy", just stretched cubes aren't going to cut it. At least invest in some more detail.
Overall, a great game. I really hope this review helps you in advance.
