THANK YOU EVERYONE WHO'S PLAYED SO FAR! We appreciate the feedback and kind words, you all rock!
Just a few tips if you are having trouble progressing:
DONUT LEVELS RUN FOREVER:
There are two Donut levels that will run forever if you don't fail. These were meant to be harder but you will probably be able to make some good consistent donuts pretty easily. Have fun making some tiremarks but when you are done, just move out of the circle to go to the next challenge. It will not hurt your score.
IF YOU WANT TO VIEW THE ENDING CUTSCENE WITHOUT BEATING ALL THE LEVELS:
Go to Challenges from the Main or Pause menu, select Donut II, then drive out of bounds. This is the last level in the game so once you lose Donut II, the ending cutscene will play. Enjoy!
