Phineas And Ferb Monster Hunters

You control Phineas and Ferb, who are positioned on either side of the screen. The goal is to stop a monster from stealing cookies that are lined up in the middle. You use your mouse to click on the monster as it pops up from different holes, trying to bonk it on the head before it can grab a treat. The monster gets faster as you progress, and you have to watch both sides of the screen to react in time. It's a test of simple reflexes and timing, without any complex controls or levels to get through. The game feels like a quick, frantic race against a hungry pest.
