Игра очень проста. Нужна поймать как можно больше фруктов. Каждый фрукт это определенное кол-во очков, которое зависит от выбранного уровня.Так же падают овощи. Если Вы ловите их, то они отнимают у Вас определенное кол-во очков. И фрукты и овощи падают с разной скоростью, которая зависит от уровня. Так же есть 2 бонуса: +50 и EndGame. Если Вы словили + 50 то ваши очки в корзине увеличились на 50 очков, если словили EndGame, то Вы проиграли. Эти 2 бонуса всегда падают быстрее.
Алгоритм таков: Генерируется случайное число, для оси y, затем еще одно для выбора фрукта или овоща. В зависимости от заданных параметров фрукт или овощ летит вниз с определенной скоростью. Проверяется столкновение с корзиной, или промах.
