First, the good:
The art is top-notch, absolutely beautiful.
The soundtrack is also excellent, although you can initially turn the volume down a bit; I only noticed the volume settings halfway through.
The concept is also great, like something new.
A bit of a downer:
The puzzles are too simple; they're solved right there and then, without even having to think. This is likely due to the time constraints, but I would have liked at least a little more thought.
Overall, the game is great, definitely worth playing.
