Thanks for playing the game! I don't know if the shop prices ever got balanced, so they could be a bit off. I am also super curious, what did you find surprising about the controls?
Dumb as this sounds, it took me a second to realize that you need to be moving in order to turn. I spent like 10 seconds driving straight into a wall.
That's great! I can definitely understand the confusion, and I'm glad you were able to figure it out and have fun!
