CatBun Idle is a pixel art idle RPG where you recruit an ever-growing crew of
catgirls, bunny girls, wolves, fairies, and dragons and send them to fight
through 40 hand-crafted areas — forever, even when you're not playing.
Tap to deal damage, trigger skills at the right moment, and push to the final
boss. Clear it and Prestige: trade your progress for Stardust, upgrade
permanently, and go again faster and stronger.
Five playable heroes, each with a unique passive. Matsu hits hard from the
start. Miya boosts tap damage. Riku amplifies auto DPS. Cleo showers you in
gold. Kaos extends every skill. Unlock them as you progress and switch freely.
40 companions across 4 tiers — catgirls and bunnies in tier 1, wolves and kitsune in tier 2, shadow cats and crystal bunnies in tier 3, void fairies and chaos heralds in tier 4
Every companion upgrades at levels 10, 25, and 50
25 pair synergy bonuses that multiply your whole crew when both members are levelled
Click companions build tap damage; DPS companions run in the background
Beat area 40 to Prestige — earn Stardust and spend it on 16 permanent shop upgrades
20 Prestige Talent milestones unlock automatically as your prestige count climbs
At prestige 10, Ascension opens — a second progression layer with its own Moondust currency and shop
An Energy Bar system replaces cooldowns once unlocked, letting you chain skills freely
4 active skills: Cat Frenzy, Rally, Gold Rush, and Catball
Boss fights with shield cycles, enrage at 25% HP, and a 30-second timer
3 daily missions refreshing at midnight UTC — kill counts, tap goals, skill uses, boss clears
Weekly challenge mode, Boss Rush (40 bosses back to back), and Endless post-game mode
7 hidden upgrades that unlock silently when you hit secret stat thresholds
30 achievements tied to real gameplay milestones — no filler
Idle gold accumulates while you're away — up to 8 hours by default,
extendable via Prestige upgrades. Come back to a welcome-back bonus
and pick up exactly where you left off.
