It's not just you. It was probably a part of the over-the-summer Itch.io purge that happened. A ton of adult creators either were booted or had specific games removed because apparently payment providers Itch uses decided they didn't like what was on that platform. That, or maybe there's new management at the company or something. I'm not 100% sure what exactly caused the purge.
Well teh purge on itch and steam where started by collective shout (australian feminist group) because of teh game "no mercy" (it had incest, rape etc in it). they email bombed visa and mastercard. which resulted into vis and amstercard forcing itch an steam to censor stuff or purge.
this feminist group is basically dictating now what we can buy or not. in the same time the UK government brought up the online safety act which is basically that all UK citizens need ID verifaction to view anything that could be viewed as unsafe for children.
and since a couple of month people fight back and it is basically a tug of war. even the japanese goverment is involved and protects the rights of hentai artists etc
and that i just surface level
