this game is sick. i noticed that your number of double jumps should save up but it hasn't worked for me. Also, I think that the power ups should not have a time limit, but they should run out when you hit an obstacles and/or go back to 0 mph. When you collect all the items and get fly mode, the music should change and you should feature a guitar solo by me. Lastly, I think the main character should be comically drawn tire that makes car noises. Just some thoughts for the sequel.
