Doraemon Mice Invasion is one of those classic Flash games where you play as Nobita, desperately trying to protect Doraemon from an army of mice—because, yeah, the big blue robo-cat is weirdly terrified of them. You just point and click to shoot the mice as they scurry across the screen, but they get faster and sneakier as you go. At first, it feels easy, but then they start coming from all directions, and suddenly you're frantically clicking everywhere like a maniac.

The art style is super simple, but there's something weirdly satisfying about nailing a mouse mid-jump. And if you miss too many? Well, let's just say Doraemon's panicked face is kind of hilarious. It's short, silly, and perfect for killing a few minutes when you're bored.
