Found y'all from your cool screenshots and had to try it out. Had a great time! My only complaint is that sometimes its a big hard to see where the road connects to the ground, so I had a few times when the car collider would get stuck between the road and the ground. This is expected, I just wish I could get a clearer/zoomed in image of the connecting point between my road and the little islands.
Also, a way to restart your level without losing allllll your roads would be great! Maybe a way to erase roads too to fix little errors? Honestly, this is a fun base of a game!
