Old-school, puzzle game similar to Solomon's Key.
Magicor works excellent.
This is a cute game. It is very difficult and not for the faint of heart. If you like challenging your wits to their end, this is it. I only have one question, how can I disable or modify the fullscreen mode? My minimum screen size is 1280x1040. My nephew loves BBQing the penguin and cannot understand why fullscreen messes up my computer.
