Solid concept and execution, I had a lof of fun playing it! You want to try again and again, pushing multiple blocks at the same time out of the platform is satisfying, the difficulty feels balanced (for me at least). The car control is a bit "all or nothing" so it's a bit hard when you want to turn, which can be a take for your game, but I feel like an "inbetween" would have also been nice.
Sadly, there's no sound at all, which would have been really cool :(
You did a really good job there though :)
