Great that you enjoyed the game, and thank you for the feedback!
While one of our goals was to make the players figure out the controls and all the wired quirks of the car, a tutorial would most likely be a great addition for a full game. One other thought I had was to make an indicator arrow, in which direction the car will move, that would vanish after some time. This could probably also help when starting the game...
Anyway, thank you for playing our game! :D
