Hello, thank you for joining my stream! Here's a written review for you.
For a first game, this is pretty good. I would suggest making a tutorial stage to let the player understand the controls, and learn to shift. If you weren't there, I wouldn't have known.
Also, the car is a bit too fast, maybe give the car some time to accelerate. I keep running into the walls and it's a bit difficult to control.
When the car breaks down, it's cool that you have to restart the car.
You have a very good idea going on, so keep up the good work!
