A decent puzzle game with a few annoying issues
If we start with the good stuff, I actually thought it worked pretty well on the iPhone. The controls are spot on and the puzzles made use of the phone in some fun ways. I've tried first person puzzles before (like Myst, or Return to mysterious island) and I've always been a bit frustrated with how easy it is to get lost or miss important clues. This is (mostly) not a problem here and makes the game more about solving the puzzles, than about finding them.
There are unfortunately quite a few puzzles that are REALLY hard, if not impossible. Without any clue (that I could find) you have to use your phone in a few different ways that I don't understand how anyone ever could figure out by themselves. There are also a few cases where you have to do some real pixel hunting to find the things you need to pick up.
All in all, a pretty descent puzzle game with some annoying issues
