About Necrotic Dungeon
A single-player dark-fantasy escape game in the browser, which its page calls “A Medieval Escape Game” and its official submission pitches as a love letter to 80s dungeon crawlers. You work your way through a run of illustrated scenes, among them a forge, a cathedral and its interior, an angel chapel with a bleeding statue and a crypt, finding keys and tools, opening locked doors and coffins, equipping weapons and a shield, and fighting bosses with their own health bars. A speedrun mode times you from the moment you grab the key to the death of the first boss. The entrant names old-school dungeon crawlers, Dungeons and Dragons and dark fantasy as inspiration. It was made for the Cursor Vibe Jam 2026, whose rules required at least 90% of each game's code to be written by AI; the official submission lists Lovable, an AI app builder, as the tool. It finished 57th of 945 entries. Free, on desktop and mobile browsers.
How it was built
Partially verifiedLovable, an AI app builder that writes and hosts web apps from prompts. In the official Vibe Jam 2026 submission the entrant lists Lovable as the tool and answers Yes to the AI-written field. No devlog describes how Lovable was used or which model ran it, and the submission covers the jam version only.

- ObservedThe game page still carries Lovable's default metadata (author “Lovable”, twitter:site “@Lovable”) and a lovable.app preview image, which fits a project built in Lovable; it does not show how much of the code the AI wrote. — necroticdungeon.com
Built for the Cursor Vibe Jam 2026 with React and Vite, with Lovable named as the tool. The game is a single-page web app that swaps illustrated scene backgrounds and clickable objects, with no 3D engine.

Verification notes: Tool (Lovable, recorded as an unlisted tool), engine, genre, pitch, inspiration and the multiplayer (No) and mobile flags from the entrant's answers in the official Vibe Jam 2026 games data (submitted 18 Apr 2026; final rank 57 of 945 entries, no award); rule 3 on the jam page requires at least 90% AI-written code. Developer unknown: the jam data gives only the X handle @barrio08001, whose profile has no bio or website, and the game page names no one, so the record uses the handle. Team size is not stated. Scene names, items, boss health bars and the speedrun rule come from text in the game's script; some internal scene labels in the script are in French, which is not presented as a language option. The script calls no outside services apart from the jam widget and the host's own analytics, and it links a Discord invite; no calls to AI services were found. Whether the scene art was drawn by hand or generated is not stated. The jam page's widget counter showed 409 plays for necroticdungeon.com on 4 Nov 2026 (observed; plays are sessions, not players or downloads, so not recorded as a metric). The release date is not stated; the jam submission is dated 18 Apr 2026.
