Where's My Perry?

Where's My Perry? is a puzzle game based on the concept of Where's My Water? as a spin-off. It is themed based on the Disney animated TV series Phineas and Ferb and has Perry the Platypus (Agent P) as the main protagonist. He works for the OWCA (the Organization Without a Cool Acronym) led by Major Monogram and needs to prevent the plans of the mad scientist Dr. Heinz Doofenshmirtz who has trapped Perry inside tubes. Just like the original game the gameplay is based around guiding water to Perry's location, finding a way around Doofenshmirtz's 'inators' that affect the water.

The game is split up into different missions that consist of five levels. To complete a level a sufficient amount of water needs to be guided towards Perry. This is done by swiping across the screen to remove dirt and other substances, creating a path for the water to flow. Advanced puzzles require the use of various 'inators'. The heat-inator turns water into rising steam, the cool-inator freezes water to ice and the celebrat-inator turns water into confetti. There is also lava, lasers and other types of substances that can make the water disappear. Often pipes and streams need to be used to move the water around. The game is played in real-time and the player has to react quickly to guide the water. Levels can be restarted at any moment with an unlimited amount of continues, in-app purchases are used to unlock additional content or to open up levels right away instead of progressing chronologically through each mission to unlock the next one.

The ducks from the original game have been replaced by gnomes for a secondary objective. Up to three gnomes can be collected per level by completing it regularly, while making sure the water or steam also absorbs the gnomes and no other substances destroy them. Each mission has three hidden files somewhere in the levels. By collecting all of them an additional mission is opened up where Doofenshmirtz's childhood friend Baloony, a helium-filled balloon, needs to be guided to an exit. These additional levels have a different type of gameplay. They scroll up vertically with a constant speed and the player has to clear the way so Baloony does not disappear at the bottom, while avoiding obstacles as it moves along.
