What Bongo Cat is
Bongo Cat is a desktop companion that sits alongside whatever else you're doing. Every time you press a key, the cat punches your taskbar. Typing, clicking, playing, working — all of it counts, and each press earns points. The points go toward finding hats, which is the whole point of the thing: Bongo cat needz more hatz. It's built as an idle-style simulation, so it keeps ticking along in the background while you get on with your day.
How a group plays it together
The game supports online co-op, so you and your friends can run it at the same time and compare what turns up. There's a shared item drop pool with clearly stated odds: Common at 90%, Uncommon at 9.5%, Rare at 0.49%, Epic at 0.01%, and Legendary at 1 in 500000. Those numbers are marked as subject to change. The fun of it in a group is seeing who pulls the odd hat and who keeps stacking commons, since everyone's cat is working while they type and play.
Before you start
Expect a low-effort, relaxing loop rather than a game with levels or objectives. You get your own bongo cat and a wide range of customization options, so each person's cat ends up looking different. It's tagged as cute, cartoony and colorful, and it's based on the artwork and meme of @StrayRogue and @DitzyFlama. It runs as a casual idle piece of software — you don't need to sit and play it, you just need to be using your keyboard.
