About Epos of Origin: Idle Reign
A free idle town builder in the browser, in an early test build. You are Millie, successor to the Demon Lord, watching over a town that runs itself: imps haul resources, visitors spend their gold, and demon heroes train, buy their own gear, bond with each other and plan their own dungeon runs from the tavern. You build farms, quarries, the Goblin Merchant, the Soul Well, the War Forge and more, collect tolls and sell spare food and stone to caravans, watch for human scouts in disguise, and defend the south gate with towers, guards and Millie's Overdrive. Rebirth burns the town down for permanent perks. Boosts are earned by playing minigames, never by watching ads: six quick building boosts and four larger ones, including a rhythm game in the tavern with five original songs, a royal court where you judge petitioners, a parry-and-dodge guardian duel and a memory game in dark, trapped rooms. The town keeps working while you are away. It plays on a phone or a computer, and progress is saved in the browser. The developer, a solo developer who goes by Origin, says they design, draw, direct and playtest the game but do not write code: Claude writes it, in Godot, and every decision goes through the developer. The art starts as the developer's hand-drawn concepts refined with AI tools, and the music and lyrics were made with AI tools (YuE2). Free on itch.io for every update up to 1.0; the developer plans a PC version on Steam at 1.0, with no ads, in-app purchases or pay-to-win.
How it was built
Partially verifiedIn the description of the YouTube devlog “How Idle Reign Gets Made: a Non-Coder, an AI and a Lot of Playtesting” (31 Oct 2026) the developer writes: “I'm Origin, a solo dev. I design, draw, direct and playtest Epos of Origin: Idle Reign, but I don't write code. Claude, an AI, writes it, and every decision goes through me.” Its “How it's made” section adds: “Code: written by Claude (an AI) in Godot, directed and playtested by me.” The video's chapters describe the process from a playtest note to release: the idea, planning together, building it, testing (829 checks), simulating hours of play, screenshot reviews and the developer's own review. The Claude model and coding interface are not named.
- DeveloperThe itch.io AI disclosure ticks AI Assisted, Code, Graphics, Sounds and Text; the page credits music made with YuE2. — itch.io
Made in Godot by one developer who designs, draws, directs and playtests while Claude writes the code; features usually start from playtester notes and go through planning, building, automated testing (829 checks per the video), simulated hours of play, screenshot reviews and the developer's own check before release. Art: hand-drawn concepts refined with AI tools, then cleaned up and recoloured in Adobe software. Music and lyrics made by the developer with AI tools (YuE2); sound effects from Pixabay. The itch.io version has gone from 0.1 to 0.6 in its first ten days.

Verification notes: AI use from the description of the developer's YouTube devlog on the channel EposOfOrigin (31 Oct 2026), re-read through YouTube's own page data on 8 Nov 2026; the itch.io page and devlogs re-read the same day. The video was not watched; the chapter titles come from its description. “I don't write code. Claude, an AI, writes it” is read as Claude writing the code; no share is stated, so none is recorded. Developer: a pseudonymous solo developer who writes in the first person as “Origin” (signing devlogs “Origin” TheOriginProject; itch.io account EposOfOrigin); no name or location is stated. An itch.io comment reply by the developer mentions local testers and uses “we” about monetisation plans. Plans for Steam (at 1.0) and a mobile store version are the developer's; neither store page was found. itch.io: published 28 Oct 2026, 19:40 UTC, updated 6 Nov 2026 (update 0.6), status In development, HTML5, Godot; no rating or download count shown. The Godot data pack (about 119 MB) was not inspected; no source mentions AI at play time. Genre from the itch.io page (Simulation, Rhythm; idle town builder). English only as observed. The game was not played.
