Funeral of Paradise - BL (Boys Love)

The developers describe how their game uses AI generated content like this:

Funeral of Paradise uses generative AI tools in the creation of some of its content. Certain visual assets in the game were produced with the assistance of generative AI and were then reviewed and edited by the developer. All such content has been checked to comply with Steam's guidelines and applicable laws.

Required on Steam store pages since 2024. It covers content that ships in the game, on its store page or in its marketing — Valve does not require a disclosure for AI tools used during development, so this says nothing either way about how the game was made. Check it on Steam.
