The file size is the only thing they have in common. The Uploader uses the Names, game descriptions and pictures of other NSFW/Adult games and I don't really want to bad-mouth the original games but if you look at the patterns I describe it should be easy to find them. All are uploaded by different Accounts with the comment section being disabled and no links to for example a Patreon or a Discord. The person has uploaded about 20 or more "games" in the adult section in the last few days.
