He was complaining about the demo being considered nsfw, despite the naughty bits not being in the demo version. Only in the full version (that is not yet ready, but is promised to be 18+).
What I meant was, that I do not know if such a demo version would be considered nsfw by itch policy or not. Imho, it should be. Because, sfw gaming is not the target audience for the final product, so why show it to such accounts.
