What Is Brush Jjaemu?
Brush Jjaemu (째무를 빗질하기) is a viral reflex and timing game created by Korean indie artist artbyeori. You are hired to groom Jjaemu, an adorable but short-tempered orange tabby cat. Brush his back as fast as possible to build your score, but freeze the instant he whips around to stare at you. Getting greedy with your strokes triggers petting-induced aggression, ending your run with a swift bite.

How to Play Brush Jjaemu
Click and hold the left mouse button, or tap and hold on a touchscreen, to brush Jjaemu's fur and build up your grooming score. Jjaemu turns his head at unpredictable, randomized intervals. The microsecond his head rotates, release all input and remain completely motionless. If you are caught brushing while he faces you, Jjaemu lunges with a sudden jumpscare bite, triggering an instant 'YOU DIED' game over.
Controls
- Mouse (Desktop): Click and hold the left button to groom; release immediately to freeze.
- Touch Screen: Tap and hold anywhere on the cat's back to brush; lift your finger to stop.
- Pro Tip: Keep your finger or cursor hovered close to the cat during pauses so you can resume brushing instantly.
Objectives
- Brush Jjaemu continuously while his back is turned to maximize your score.
- Release input immediately when the cat begins his turn animation.
- Read subtle visual cues like ear twitches to anticipate turns before they happen.
- Resist greed on each stroke to survive longer rounds and chase a personal high score.
Gameplay Mechanics
Brush Jjaemu pairs cozy, hand-drawn pet grooming visuals with suspenseful, hair-trigger reflex challenges. The contrast between calm brushing sounds and the sudden shock of being caught creates an addictive risk-versus-reward dynamic. Reading micro-cues like ear twitches and shoulder shifts turns a simple grooming chore into an intense test of discipline and reaction speed.

Tips & Strategies
- Watch the ears: Jjaemu's ears give a faint twitch a split-second before he turns—use this as an early warning.
- Use short stroke bursts: Brushing in controlled 1-2 second bursts makes it much easier to halt instantly than holding continuously.
- Beware the double turn: Jjaemu can turn back-to-back in quick succession; wait until his posture fully resets before brushing again.
- Stay relaxed: Tense fingers delay physical release reaction times by vital milliseconds; keep your hand loose.
FAQs
How do you score points in Brush Jjaemu?
You earn points by dragging the comb across Jjaemu's fur while his back is turned. Faster, continuous strokes build your score more quickly, but increase the risk of getting caught when he turns.
How can you tell when Jjaemu is about to turn around?
Watch Jjaemu's ears and head angle closely. A subtle ear twitch and slight shoulder shift precede his full turn animation. Recognizing these micro-cues gives you the split-second advantage needed to stop in time.
What causes the 'YOU DIED' game over screen?
If you continue clicking, dragging, or touching the screen while Jjaemu's eyes are locked on you, Jjaemu immediately bites with a startling sound effect and triggers the game over screen.
Can you play Brush Jjaemu on mobile devices?
Yes. The game fully supports touch input. Tap and hold on Jjaemu's back to brush, and lift your finger completely off the screen to freeze when he turns.
