Soo while I'm not a fan of lolicon content, a viable workaround could be to remove lolicon content from the Steam version, which can then be added back in with a patch uploaded here. If so, I think Mofu would need to add a disclaimer to the in-game menu that says that there's additional content available with a patch from here on itch (or wherever it'd be uploaded to). And of course, the full game would be available here on itch and elsewhere.
A bit cumbersome perhaps, but at least it'd work well to remove the risk of that happening.
