About Abnegate
Abnegate is a short 2D action-adventure demo for the browser. You enter the abandoned Frosty Hollow mall to find out why no one has ever come out, and capture the spirits that haunt it. Per the developer, each type of ghost has its own capture pattern and there are unique boss battles, and you gain abilities that open gated areas; the developer would not call it a Metroidvania. The story is light and told mostly through play and still images, with little text. The developer names Ghostbusters and Luigi's Mansion as inspirations. The workflow, per the developer: the ideas went into ChatGPT to shape a complete game design document, and that document went to Claude with the request to build one self-contained HTML file; after one session there was a playable version, followed by playtesting and changes. It is best played with a controller; the developer says mobile controls are not ready yet. A free demo on itch.io; the developer says the full game is coming.
How it was built
Partially verifiedIn a post on r/aigamedev (6 Nov 2026, UTC) the developer writes: “The game was built as a single html file using Claude.” Describing the workflow: “Once I had the full game design doc entirely finished, I took that over to Claude. I told Claude I wanted it to build me a single contained HTML file using my GDD. I'm using a Claude pro subscription and set it to max for this step. After that single session I had a fully playable version.” Playtesting and changes followed, using medium or low effort for simple changes such as enemy counts and max for graphical changes. No model is named.
Used for the design document, not the code: “I dumped all my ideas into ChatGPT to help form a cohesive game design document. I told it to give me a list of everything that needs to be decided before building.”
A complete game design document was shaped with ChatGPT; Claude then built the game as one self-contained HTML file from that document in a single session, and the developer playtested and asked for changes. The itch.io build is one HTML file of about 360 KB that loads no outside scripts apart from itch.io's own player script and calls no AI services.

“I told Claude I wanted it to build me a single contained HTML file using my GDD.”Verification notes: AI use and workflow from the post by u/Abnegatethehate on r/aigamedev (6 Nov 2026, 14:22 UTC), read from the Arctic Shift Reddit archive on 8 Nov 2026; the post links the itch.io page. Setting, length, controller advice and genre from the itch.io page, re-read on 8 Nov 2026 (published 3 Nov 2026, 13:47 UTC; updated 6 Nov 2026; status Released, HTML5; tags include Horror and Creepy; AI disclosure “AI Assisted”). The page says “Full game coming soon”, so the listing is recorded as a demo. Ghostbusters and Luigi's Mansion are named by the developer as inspirations; the game file contains no Ghostbusters or Luigi's Mansion names, so no IP notice is added. The post does not give a share of AI-written code; it says Claude built the game file from the design document. The HTML file was checked and contains no AI service addresses. Team size and location are not stated. itch.io shows no rating or download count. The game was not played.
