I had planned to make multiple scenario's which ramped up in difficulty, so that the player has time to figure out the controls at the start in a level that is basically drive from A to B. Though adding a tutorial popup that explains how to do that is definitely a good idea.
The game is quite complex for a gamejam and I didn't think I would be able to finish it in time. Though I'm glad I tried as I did succeed in implementing the basic idea of the game.
