Download: Where's my Perry?

For anyone who hasn't watch the excellent cartoon Phineas and Ferb, Perry is their pet platypus who lives a double life as a secret agent called Agent P. It's rather surreal but very good fun. In this physics based game you must help Agent P through a series of trials by manipulating water, steam and ice.

In order to complete levels a certain amount of water or steam must be collected. Channels can be made through the earth to guide water and steam. To complicate matters there is sludge that must be kept away from the collector as well as ray guns that heat up or cool down the water.

For an even greater challenge, each level has three gnomes that require either water or steam to collect. Collecting all the gnomes gives extra points and a certain number must be collected in order to progress to the later chapters.

There are also bonuses for finishing with a surplus of water or steam as well as secret files that can be found behind the earth on some levels.

If the 120 levels weren't enough there are also some special challenges such as finishing some levels without collecting a single gnome. This can be harder than it sounds. Some of these challenges are included with the game but the full 50 levels costs an extra 69p

It should be pointed out that this is basically the same game as Where's my water? (link to iTunes). This isn't a bad thing, but you might want to think how much of a Phineas and Ferb fan you are before parting with another 69p. There's even a link to a demo of Where's my water in the main menu.

If you like puzzle games, this is a great app, and even better if you are a fan of Phineas and Ferb (as we are).
