This is possibly the best puzzle game I've ever played. You have a variety of puzzles where you have to use equipment in a particular way. You have to discover how the quipment works, and then how to use it effectively. Good Points are that you don't have to complete every challenge to make progress. You aren't given any real hints, but you can always try nsomewhere else and come back to the problem area later. Thje scenery and 3D effect is brilliant and attractive. There are bonus stars to be earned. I'm loving it!
