This is a fun little car game. Can't really call it a racing game but a platformer instead. A car platformer would be more fitting. It's likely a combination of not having a clear path and too many death options. But as a plaftformer, it's very nice. The controls also feel like it's built for a platformer too, with quick turning, high acceleration and deceleration, but with a lower-than-usual top speed. It's quite fit for this game I'd say. The are three levels too and I apperciate your effort of make these large levels to be played with. Nice job!
For a bit of criticism, I'd say the camera is very annoying and can't really see where your car is heading towards. Using shift for hand break and space for jump is a bit disorientating, but it's probably just me getting too used to press space for hand break instead. I'd also say the loy poly scene with single colour texture makes the edges of the platforms very hard to see, as they blend into each other. Consider adding a bit more texture or adding something in the level to signify that edge.
Anyway, this is a nice game, and you should be proud of yourself for making this! Keep up the good work!
