Kye

This is a shareware puzzle game, registration originally designed to support the charity "Save the Children." In it, you play a green ball whose object is to go through the maze and get all of the diamonds. There's many enemies that you have to watch out for, but you're also given many tools to help you deal with the enemies. You're given a hint at the beginning of each level, and the level name at the end. Also, the game comes with a level editor, where you can create your own levels. Those can be loaded into the game proper and played by you or your friends.
