Black Cat Brushfight

Idle RPG: Paint up, gear up—crush the colorless white cats!

Color is power. And the world is trying to steal yours.

Step into a hand-drawn world where a black cat hero fights back against colorless white cats who want to drain all color from existence. Armed with brushes, pencils, and improvised weapons, you’ll forge, paint, and battle your way across evolving eras of creativity.

Are you ready to paint the world again?

Forge Tools Across Creative Ages

Begin with simple doodle tools — rough pencils and sketchy gear — and forge your first equipment. As you progress, upgrade your workspace to unlock new creative eras, from Crayon Age to Ink Age, Digital Age, and beyond. Warning: every upgrade makes you stronger… and more tempting to your enemies.

Brushfight Against Colorless Cats

Face off against white, monochrome enemies determined to turn you gray. Equip your painted gear, use expressive skills, and overwhelm them with color. Each battle is a fight for contrast — and identity.

Paint to Power Up

Your hero starts losing color over time. Re-paint yourself to stay strong. The more color you restore, the stronger your attacks, defenses, and special effects become. Let yourself fade… and you’ll pay the price.

Research New Styles

Unlock new techniques in your style tree. Faster strokes, thicker outlines, explosive splashes, or precise linework — choose how your black cat fights and paints.

Collect Creative Companions

Meet quirky cat companions inspired by doodles and sketches. Each one adds unique effects to battles, from splash damage to color regeneration. Train them and build the ultimate creative squad.

Compete in a Colorless World

Challenge players from around the world. Prove whose brush is sharper, whose style is bolder, and whose cat refuses to fade. Climb the global leaderboard and leave your mark in a world that wants everything gray.

Sketch, Chat, and Connect

Chat with other players, share strategies, or just admire each other’s styles. This is a living doodle world — and it’s always evolving.
