This one has a lot going for it. The visuals are gorgeous, the story development as you solve puzzles is great, I love puzzle games which dole out story as a reward for puzzling. I like that you have multiple control schemes (when I discovered accidentally that I could move with the mouse it was a nice surprise).
Some of the puzzles are a little obtuse, but some are quite clever and satisfying. The long maze sections to get between rooms can be a little tedious, especially with the character getting caught on corners, etc.
But overall I think it's a very creative entry and I like what you're doing with it!
