About Sunderbound

A browser text RPG and interactive fiction game: you play a rookie hunter clearing portal dungeons in a city, and a run can change your character's body and mind. Version 0.1.0 is a vertical slice with one dungeon, three playable races, the first story act, a simple combo combat system and multiple endings. The developer says the narrative is their own and that the game's frameworks, systems and structure are co-written with Claude Code. It is free to play in the browser on itch.io and is still in development.

Verification notes: AI use from the developer's 0.1.0 devlog and the itch.io AI disclosure; release date from the devlog post date (itch.io shows only relative dates). The itch.io page states an MIT code licence but links no repository, so the game is not marked open source. Not run in a browser by us.
