About Agent P Strikes Back
Agent P Strikes Back is a 2D side-scrolling platformer game based on the Disney animated series Phineas and Ferb. Released in 2011 as a Flash-based browser game tied to the movie Phineas and Ferb the Movie: Across the 2nd Dimension, it lets players take control of Perry the Platypus, known as Agent P, in his secret agent persona.
The game is set in the alternate “2nd Dimension” where an evil version of Dr. Doofenshmirtz has captured nine agents from the Organization Without a Cool Acronym (O.W.C.A.). Major Monogram briefs Agent P on the mission: infiltrate Alternate Danville, rescue the agents across three levels, battle robotic enemies like Norm Bots, and ultimately confront the villainous Alternate Doofenshmirtz.

How to play
Controls
- Left Arrow: Move left.
- Right Arrow: Move right.
- Up Arrow: Jump (Agent P can double jump and cling to walls for added mobility).
- Spacebar: Attack – Disarm Norm Bots to grab their arm, then use it to shoot projectiles at enemies until they’re destroyed.
- Down Arrow: Drop the held arm (useful if you need to regain jumping abilities while holding one).

Start in Alternate Danville and move through side-scrolling environments filled with platforms, pitfalls, and enemies. Encounter Norm Bots along the way – approach them, press Spacebar to remove their arm (disarming them), and then hold the arm to shoot it as a weapon. Avoid hazards like lasers and pits, and use platforming skills to navigate the neon-lit, dystopian cityscape. The levels increase in difficulty, with more complex layouts and tougher enemy placements.
