So, for those asking about it, technically releasing this game, especially for free, isnt illegal. There have been several clones of Minecraft that were blatantly trying to trick k*ds into getting it, and those weren't removed.
This, however, should not have been released. Without even playing it, it seems like it's just using the source code from a Unity-based minecraft recreation, but it replaced the default character model with a hentai babe, as well as most likely adding a third-person camera controller by just slapping some premade code on there and not changing it. I came to this conclusion from the fact that most screenshots in the third person have a torch in the right hand corner. In base minecraft, if you go into third person, you dont see the block you are holding in the same spot you would see it if you were in third person. The third-person camera controller was probably just slapped on with no changes whatsoever.
My guess is that this is someone's first unity project or, more likely, a test game made to just try out the program that the creator decided to post online because "anime tiddy go brrrrrrrrrrrrrr"
thank you for coming to my TEDtalk.
EDIT: Just found out that this game was sold on Steam for 50 cents, possibly more. Yeah, this definitely seems like a game meant to trick horny people.
