Brush Jjaemu's orange fur gently — but FREEZE the instant this moody cat turns around!
Brush Jjaemu (also known as Brush Jaemu, or 쟈뭐 브러시 in Korean) is a viral browser game created by Korean artist @artbyeori (이오리). First published on itch.io in April 2026, the game exploded across Reddit, X (Twitter), TikTok, and Instagram — earning the title "the Dark Souls of cat grooming."
The game features an orange tabby cat named Jjaemu. Your goal is simple: brush the cat's fur by moving your mouse or finger. But Jjaemu is unpredictable — when the cat whips around to stare at you, you must freeze completely. Any movement while being watched means game over. It's essentially "Red Light, Green Light" meets cat grooming.
Brush Jjaemu hit the perfect viral formula: it's instantly understandable, deeply relatable (every cat owner knows the danger of over-petting), and produces shareable moments. The game's tension between gentle grooming and sudden cat attacks creates genuine jump-scare reactions that perform extremely well on short-form video platforms.
The game first gained traction on r/OneOrangeBraincell on Reddit (6,000+ upvotes), where the orange cat theme resonated with the community's love for unpredictable orange tabbies. From there, gaming outlets like Dexerto picked it up, TikTok creators started posting their reactions, and it snowballed into millions of plays within days.
Brush Jjaemu was created by artbyeori (이오리), a Korean artist and indie game developer. The game was built using the Godot game engine and exported as HTML5 for browser play. The original is hosted on itch.io. Jjaemu is based on artbyeori's real orange tabby cat.
