I have a student who created the following app. When you go through the game and click Review on the last slide, it goes back to the start screen and the scores are reset to zero, BUT when you play the game the second time, the score/incorrect is being changed by multiples of 2. When you play a 3rd time, the scores are being changed by multiples of 3 and so on.
Space Review Game
Any help would be appreciated.
