I mean, it is technically his assets they're using. And because they're using his assets and programming, but have added more stuff (outside of a mod pack) and made it paid, the original developer was practically forgotten and hasn't received any money for the game he worked on programming from the ground up.
So far, you're literally the only one that even mentioned "programming" about this issue. Even HotPink didn't claim programming on their Itch.io report.
It is a common knowledge that Tentacle Locker and Lovecraft Locker are made from two separate game engines, which means two separate programming languages.
At least try to research harder about the stuff you claim, it's just embarrassing you're randomly throwing things in here.
Even if the programming is on a different engine, it can be the same program and same assets. It's idiotic to even claim that I'm mistaken. There are thousands of games that have identical programming on seperate engines. So, shut up on that.
Saying that information about a indy porn game that <300 people have purchased is "common knowledge" is also incorrect, so shuttith.
Regarding HotPink, he's a moron. The fact of the matter is, in a courtroom, this is theft of intellectual property. Get off itch -- you're 16 years old and you haven't even paid for the game.
