Where's My Perry? is weirdly named; at all times you know exactly where your Perry is (its actually so named because this is kind of a sequel to Where's My Water?). Perry is hiding in a tube, waiting for you to use your six year-old powers of deduction to open a door for him. Yes, Where's My Perry? is aimed squarely at children and/or people who are really not good at puzzles. So, if you're constantly looking for that great new puzzle game to keep you occupied, you won't stay with this one for long.
Where's My Perry? looks like it has a lot going on in it, but it really doesn't. All you have to do is move water into a hole on the floor, or move steam into a hole on the ceiling, or whatever. You move the H2O by cutting through dirt with your finger. So the extent of the game is you directing water toward where it needs to go. If there were a version of this game that required you to use your phone's tilt sensor, you might have a physics-based puzzler that is complex and interesting. Unfortunately, the puzzles tend to be very simple and not challenging. At most, an experienced puzzle player will have to try a given puzzle twice before moving on, and even doing a puzzle two times will only take you 20 or 30 seconds.
If you're bad at puzzles, or if you're looking for something totally mindless to do as you're sitting on the couch half-watching TV at the end of a long day, then this game might be for you. But for most consumers of phone games, Where's My Perry? will not satisfy that puzzle itch. Those folks will probably do 10 or 20 puzzles and then play something else as it's just not challenging enough.
