Extermination of Flies

Swat every last fly before the room turns into a buzzing nightmare.

I didn’t expect to lose twenty minutes to a fly-swatter sim, but here we are. You get a screen, a swatter, and a handful of flies that absolutely refuse to sit still. The first few seconds feel almost too easy—one or two flies, lazy loops, satisfying squash sounds. Then three more show up. Then the original ones start speeding up. Suddenly you’re flailing at the screen like a caffeinated barista trying to kill a wasp. What got me hooked is how the game punishes panic. Swing wildly and you’ll miss by a pixel; stay calm and wait for a landing, and that splat is deeply cathartic. There’s no health bar or timer pressure at first, but the flies multiply on their own clock. One time I had five of them circling a single pixel of screen real estate, and I actually held my breath to time the hit. The hitbox feels fair—maybe a touch forgiving on the edges, which keeps it from being infuriating. The visual style is simple, almost cheeky: cartoon flies with exaggerated wings, a swatter that leaves a little impact effect, and a subtle buzz that grows louder as more flies appear. It’s pure reaction-based arcade nonsense, and it works. If you need a quick rage-release or just want to see how long you can keep your composure, this one’s a nasty little time sink.

Wait for a fly to land on a surface before swinging—mid-air swings rarely connect. Don't chase the fastest fly; clear the slow ones first to reduce visual clutter. Keep your cursor near the center so you can reach any corner quickly. Listen for the buzz getting louder—usually means a new fly just spawned. If you miss twice in a row, reset your hand position; don't spiral into wild clicking. Play with sound on; the splat feedback helps you confirm hits instantly.
