Remember when Flash games were just pure, simple fun? Phineas and Ferb: S'no Problem nails that vibe. You start stacking snowballs into this ridiculous mountain—like, way taller than Perry the Platypus should logically allow—while Phineas and Ferb prep their boards at the bottom. The physics are goofy in the best way; sometimes your snow pile leans like a Jenga tower about to collapse.

Of course, Doofenschmirtz shows up with some "Snow-Melter-Inator" nonsense, so you're racing against his slow-motion laser beam. The higher you build, the crazier the ride gets—Ferb does this little spin move off jumps that always cracks me up. Classic cartoon chaos, zero stress. Just don't expect it to last more than a few minutes before you're back to the title screen grinning.
