From wenqing gao:
This game needs scientific knowledge. Your target is to win by scoring high. In this game, you have to shoot all of the falling red apples so that they would not hit Newton. The golden apples are beneficial for Newton in his pursuit of success in science. Your score would be submitted to Game Center as long as you grant permission. Of course you might want to show off your score to friends through social media.PS:Congratulations if you are the first to score 88 points in game center! Let me know and get the 1,000 cash reward!!!
