Nice game. I liked your use of the theme. The ability set you chose is pretty good for a puzzle game. I can envision some cool puzzles in a full version.
One complaint though - The camera was too zoomed in for me so I couldn't see entire tutorial text at once. It also made it hard to tell what I was supposed to do at first in each room. Not sure if that's a browser thing. The puzzles were simple enough it didn't get in the way, but I think if it was zoomed out more, you could make some more complex puzzles.
