Changes :

 i already have the code for this game but i want some changes. change the fruits to cubes , Add title ( classification of numbers ) , change the main character to boy, Add to the main menu two options which are odd numbers which has a red color or even numbers with green color ,, once the user choose odd or even numbers he must collect the cubes that has what he selected, all the odd numbers cubes will have same color which is red and all the even numbers will have same color which is red. If he choose odd numbers then he collect one of the even cubes the game will stop.

 NOTE: Those games are for small children so i want the game very simple.
