What difficulties did you have with programming this game? How did you fix them? Be specific.One of the difficulties I had programming this game is setting the high score. I fixed it by turning on the slider.

What changes to the tutorial game did you add? Why and how?Instead of a circle track i made it to an eight looking track. I made it like that, so you have more action on pressing the A and the D key.
