Le gameplay de Fruit Ninja est très simple, il suffit de couper autant que possible les fruits lancés.
Aujourd'hui, Xiao Wu utilisera python pour simplement simuler ce jeu. Dans ce projet simple, nous utilisons la souris pour sélectionner le fruit à couper, et la bombe sera cachée dans le fruit. Si la bombe est coupée trois fois, le joueur échouera.
