About Clanbound
A free fantasy roguelike deckbuilder in the browser. You pick one of ten heroes, each with a starting deck, a relic and cards of their own, and fight through three acts to the final boss on a branching map of 15 floors per act, with merchants, campfires, treasure and events. Cards come from seven clans; creature cards are summoned onto a battle line where they attack on their own at the end of your turn and take enemy hits in front of you, while spells and attacks work at once, and creatures with Taunt pull attacks that would strike past the line. Per the itch.io page there are 224 cards (88 of them creatures), 99 enemies including 27 elites and 11 bosses, 44 relics, 12 potions, card upgrades at the campfire, 28 events with voiced characters who react to your choices, an optional hard mode and automatic saving after every room. The developer, AssetSmithy, who makes and sells 2D game asset packs, says every line of code was written by Claude Code, including the fire, heat-shimmer and depth-of-field shaders, while the developer set the direction, played every build and gave feedback; the art and music come from the developer's own asset packs, made with AI tools and reworked by hand, and the voices and sound effects were generated with ElevenLabs. The developer names Monster Train and Wildfrost as the models for the creature combat and calls the map-and-relic frame the Slay the Spire template.

How it was built
Partially verifiedIn a post on r/aigamedev (20 Sep 2026, UTC) the developer writes: “Every line of code was written by Claude Code. I set the direction, played every build and gave feedback, from ‘the shadow is in the wrong place’ to ‘make the campfire look more real’.” Per the post, the fire, heat shimmer and depth of field in the backgrounds are shaders Claude wrote, and when the first build (Unity WebGL) took close to a minute to load, Claude ported the whole game to plain HTML5 and PixiJS, 1:1 including the shaders and particle effects; the developer says both builds were run side by side on the same seeds and the combat came out identical. In replies the developer puts Claude's coding time at about six hours over two evenings, including testing, with the asset packs themselves taking weeks to months, and describes a bug fix in which Claude reproduced a reported card-drag lock-up from a player's description. No model is named.

Built out of the developer's own 2D asset packs (backgrounds, battlers, card frames, icons, UI), which the developer says were created with AI tools and cleaned up by hand, with music from the same packs and voices and sound effects generated with ElevenLabs. Claude Code wrote the game first as a Unity WebGL build and then ported it to plain HTML5 with PixiJS and no engine, which loads in a few seconds. Balancing is done by feel, per the developer.

“Every line of code was written by Claude Code. I set the direction, played every build and gave feedback.”Verification notes: AI use, workflow and the Unity-to-PixiJS port from the developer's post on r/aigamedev by u/_AssetSmithy_ (20 Sep 2026, 09:52 UTC) and the developer's replies, read from the Arctic Shift Reddit archive on 7 Nov 2026; the post links the itch.io page. Features, credits, controls, the AI disclosure and the itch.io rating of 4.0 (1 rating) from the itch.io page, re-read on 7 Nov 2026 (last updated 14 Oct 2026, 08:30 UTC; status Released, HTML5, made with PixiJS); devlog dates from its feed. The post gave 156 cards (67 creatures); the 20 Sep 2026 update raised this to 224 cards with four hero-only cards each and added hard mode, and the current page says 88 creatures. Team size is recorded as one because the post is written in the first person and the credits list only AssetSmithy for game, art and music, with ElevenLabs and Claude Code as tools. The itch.io page shows no publication date, so no release date is recorded. The game's loader script and bundled PixiJS were checked and contain no calls to AI services. The developer names Monster Train, Wildfrost and Slay the Spire as the games the design builds on; no third-party names or assets are used, and the art is the developer's own. itch.io shows no download count. The game was not played.
