A puzzle game, it teaches you how do do all the puzzles with no dialog. It was at it's best when the puzzles took advantage of the 3d space rather than just being a line puzzle. By the end of the game I would forget how different line puzzle rules worked and have to relearn them. Fun but best with a guide nearby to get unstuck when that happens. I was ready to be done with the game before it was over but not by to much. The envirements where very nice and calming.
