It's a cool little game for sure. I think without some of the bugs, you have something that is pretty creative. I ran into some bugs where I couldn't place any walls, oil cans, etc.
Also, I think the idea would have been better executed if the car wasn't controlled, and you had to somehow guide it to the finish line by removing walls, adding booster pads, etc. Otherwise, still good work on this. Hopefully, my feedback helped!
