Brush Jjaemu is a high-stakes survival simulator game disguised as pet care released in April 2026, created by indie developer Artbyeori. The game challenges players to carefully groom a very temperamental cat while managing speed and precision. Move too slowly and your score suffers. Move too fast and, well… you get bitten. The entire experience sits somewhere between comedy and psychological pressure, which is exactly why people can’t stop playing it.
Jjaemu is the central character of the game. This orange tabby cat carries a permanently unimpressed expression, as if you’ve already made a mistake before even touching the mouse. Jjaemu perfectly embodies the classic “feline overlord” personality: unpredictable, easily irritated, and entirely indifferent to your good intentions. While the cat appears soft and harmless at first glance, its behavior tells a very different story. Jjaemu enforces strict, unspoken grooming rules, tolerating brushing only on its own terms, instantly reacting when annoyed, and delivering a bite without hesitation or forgiveness. This sharp contrast between its cute appearance and ruthless attitude is what makes the character both amusing and stressful, turning a simple grooming task into a tense, high-stakes experience.
Mess up once and you’ll be greeted with a very familiar “YOU DIED” screen, because apparently even cat grooming now borrows from Dark Souls.
