About this game

This is an idle game with rich skill development and upgrade elements.

Gameplay

At the center of the island stands a mysterious cube that constantly spits out resources. Before long, an entire stone tribe begins revolving around it in a frenzy.

Some villagers punch the cube. Others run around collecting the coins and resources scattered everywhere. And your job is to keep the whole tribe growing.

This is more than just a typical idle game. As the cube levels up, the resource cycle gradually becomes unstable. You’ll need to continuously adjust skills, professions, and growth paths to keep the entire system running efficiently.
From simple gathering to complex synergies. From a handful of tiny villagers to a massive tribe operating at full speed and impossible to stop.

The Stone Tribe

As the game progresses, you’ll gradually unlock:

  • More professions and skill builds

  • Talent combinations and temple blessings

  • Seasonal island challenges and growth rewards

  • Increasingly absurd numbers and screen-filling effects

You can play casually and let the tribe idle on its own. Or dive deep into optimizing every possible growth route and efficiency chain. Until the entire island is consumed by a flood of resources.

Features

  • Incremental gameplay built around resource flow and growth balance

  • Expanding systems of skills, professions, and builds

  • Evolves from light idle gameplay into complex resource synergies

  • Satisfying late-game explosions of resources, effects, and scaling numbers

  • Charming pixel art and a constantly thriving stone tribe

    🛠️ Patch Notes: Text & Localization OverhaulHello everyone!This update is not focused on adding new content, but rather on a comprehensive revision and refinement of the game’s text.Over the past period, I’ve received a lot of player feedback suggesting that some of the game’s terminology and mechanic descriptions were too abstract and difficult to understand. Based on that, I revisited most of the in-game text and standardized many of these concepts.Terms such as “Overlap,” “Expansion,” “Shrink,” and “Rift Space” have now been replaced with more intuitive and easier-to-understand expressions. At the same time, all related skills, talents, upgrade effects, and descriptions have been updated accordingly to ensure consistency and clarity across the board.I hope these changes help both new and returning players reduce friction when reading and make it easier to understand the core mechanics of the game.🌐 Localization & TranslationI’d also like to take this opportunity to talk a bit about localization.As a solo indie developer, I currently don’t have the resources to work with a professional translation team. Because of that, most of the localization work relies on AI tools, followed by manual review and adjustments on my side.While this greatly improves development efficiency, I’m also aware that the final text quality may not always be perfect—especially in subtle meanings, genre-specific terminology, and natural language expression.Therefore, if you notice any translation issues, awkward phrasing, or inconsistent terminology—or if you’d like to help improve the localization quality—I would be extremely grateful.You can reach me anytime via Discord, QQ, or the Steam Community to share feedback or suggestions.I read every single piece of feedback carefully.📊 Upcoming Development PlanOver the next week, updates may not be as frequent as before, as I’ll be focusing on developing a new system: a detailed data interface for in-game production and collection.This feature wi...

    🛠 Bug FixesFixed an issue where the Boxer talent “Greedy Strike” could incorrectly absorb non-copper coins.Fixed an issue where clicking on Blessings in the Temple UI could occasionally trigger the Prayer button instead.Fixed an issue where a failed “Expansion” would still play the success sound effect.⚖️ Balance AdjustmentsWinter Island completion requirement increased from Cube level 20 to 25.Increased the amount of core energy dropped per Cube level.Slightly reduced the overall heat decay rate.Adjusted the Alchemist’s “Delicious” skill: coins gained from Coalball synthesis -1.These changes mainly aim to improve the early-game pacing, where skill points felt too scarce, making it difficult for players to assemble a functional early build.At the same time, the Winter Island completion threshold has been raised to give established builds more room to scale, allowing players to better experience the late-game buildcrafting and synergy phase.
