I like the initial idea, and the title screen made me curious to test it, but I didn't really feel like I was moving the world in the game. It felt more like a weird mouse control for the vehicle.
The boats and sometimes trees moving with the camera (a little bit) tried to give this feeling I guess, but it's not very consistent, and there are a lot of elements that don't really react to the world rotating. Not sure what could sell the idea better, not an easy thing to do !
Also, I had bugs where the environment was suddenly changing, and the road just disappears and make me lose.
