Brush the cat.
Don't get bitten.
You've been hired to brush Jjaemu (째무) — a chubby orange tabby with very fast reflexes. Brush for points, freeze the second they look back, replay forever.
Play Brush Jjaemu
⚠️ Heads up: contains a jumpscare sound when you fail.
Open on itch.io ↗How to play
It's basically red-light / green-light, but the traffic light is a cat with teeth.
Click and drag the brush across Jjaemu's fur. The faster you stroke, the faster your score climbs.
Keep an eye on Jjaemu's head. A turn is coming — sometimes slow, sometimes sudden.
The instant they look at you, STOP. Wait until they look away again, like a statue game.
Brush while they're watching = chomp. Game over with a sharp jumpscare. Then you replay.
Survival tips
From players who've been bitten too many times.
- 01Brush in short bursts.
Long continuous strokes feel safe but get punished. 1–2 second bursts give you reaction room.
- 02Watch the ears, not the eyes.
The ear twitch happens a beat before the head turns. That's your cue.
- 03Stop fully — no nudging.
Even tiny movement after the turn counts as brushing. Hands off.
- 04Audio on > audio off.
The pre-turn rustle is the strongest tell. Don't mute (unless jumpscares are a problem).
- 05Replay fast.
Runs are short. The score breakthroughs come from rhythm, not patience.
Meet Jjaemu (째무)
Jjaemu is a real chubby orange tabby cat from Korea, made into a tiny browser game by illustrator and indie developer artbyeori (also known as byeorisim on itch.io).
Built in Godot, it spread on TikTok and YouTube thanks to one perfect ingredient: cute cat + sudden jumpscare. Most runs last under a minute. Most players replay anyway.
This is a fan hub — all credit for the game and the cat goes to the original creator.
Questions you'll have
Is Brush Jjaemu free?+
Yes — it's a free browser game published on itch.io by the creator. No download or signup needed.
What does Jjaemu (째무) mean?+
It's the name of the real orange cat the game is based on. Just a cat name, not a word.
Why is the cat biting me?!+
You kept brushing while they were looking. That's the whole game — freeze when they turn around.
Is there a jumpscare?+
Yes — a sudden close-up and sharp sound when you fail. Lower your volume if you're sound-sensitive.
Does it work on mobile?+
Sort of. Touch input can be flaky and the freeze detection is harsher. Desktop with a mouse is the intended way.
Who made it?+
Korean illustrator artbyeori (byeorisim on itch.io), built in the Godot engine.
Think your reflexes are fast?
The cat disagrees.
