This is really a Unique concept, I was not expecting something like this to be honest. It is done nicely as well.
The basic car mechanics are super interesting, ones that are often not really seen in any other car games so that was a real breath of fresh air.
I do also think the tutorial was a bit weird, I did not understand half of it - Maybe the font made a bit difficult to read. [grab] should also indicate that it is with the mouse button, I did not know that until I went into the actual level.
The level/s themselves are simple but really good combined with the art style. Maybe would have preferred a more variety in them but for a jam game that's still good. However doing it 9 times over is bound to get repetitive.
The sound design I thought was really well done, all the car's sound effects were implemented nicely and didn't overwhelm everything else to much(just slightly).
Also I would prefer to get back into the level faster, so the Debt/Overdue screen could be improved.
Overall I really enjoyed it and thought it was really fun to play.
