This guide describes how to use Steam Proton to play and run Windows games on your Linux computer. Some games may not work or may break because Steam Proton is still at a very early stage.

1. Activating Steam Proton for Linux:
Proton is integrated into the Steam Client with "Steam Play." To activate proton, go into your steam client and click on Steam in the upper right corner. Then click on settings to open a new window. From here, click on the Steam Play button at the bottom of the panel. Click "Enable Steam Play for Supported Titles."

Alternatively: Go to Steam > Settings > Steam Play and turn on the "Enable Steam Play for Supported Titles" option.

Valve has tested and fixed some Steam titles and you will now be able to play most of them. However, if you want to go further and play titles that even Valve hasn't tested, toggle the "Enable Steam Play for all titles" option.

2. Choose a version
You should use the Steam Proton version recommended by Steam: 3.7-8. This is the most stable version of Steam Proton at the moment.

3. Restart your Steam
After you have successfully activated Steam Proton, click "OK" and Steam will ask you to restart it for the changes to take effect. Restart it. Your computer will now play all of steam's whitelisted games seamlessly.

4. Launch Stardew Valley on Linux:
Before you can use Steam Proton, you must first download the Stardew Valley Windows game from Steam. When you download Stardew Valley for the first time, you will notice that the download size is slightly larger than the size of the game.
This happens because Steam will download your chosen Steam Proton version with this game as well. After the download is complete, simply click the "Play" button.

Tap and idle your way through 40 areas with adorable catgirl and bunny girl companions! Level up your crew, trigger powerful skills, and prestige for Stardust in this cute pixel art idle RPG with a full original soundtrack.

Tap. Idle. Prestige. Repeat.

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.

Choose Your Hero

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.

Build Your Companion Crew

• 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

Prestige, Ascend, and Keep Going

• 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

More Than Just Clicking

• 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

Offline and Honest

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.
