Simple and enjoyable, yet short!
Graphically I enjoyed the style, everything seemed relatively easy to understand and I knew what I was doing, although I wasn't sure about the achievements popping up every so often
Sound was subtle, but not too subtle that it might ruin the game itself, so many games are ruined by terrible music choice that annoys people or makes them want to discontinue playing, this was just the right touch.
Gameplay was enjoyable, yet a little easy. I cannot consider myself very good at puzzle games, so for me to be able to do almost every single room on the first try was a little underwhelming - i'm sure this game may be getting some updates for its iPhone counterpart, but as it stands, the length of the game was the biggest let down for me. Still a solid game nonetheless.
