This is freaking crazy.
The game is literally tagged as abandoned, people paid for content and the creator decided to create a whole new game. When I see devs doing this with regular games, like an early access indie game, usually the game studio/dev is doomed. The community will not forgive nor forget(usually). And yet we see people do this over and over again with adult games.
It's really interesting how this whole "adult games industry" works. Devs work endlessly on the same game, adding an astronomically high amount of characters to the game, to the point of the game being just a shell of the original premise. We see devs giving "crumbs" for content and people showering them with money, not even knowing when or if they will deliver the product. And this is totally sustainable for the devs, since they get their paycheck monthly. This is nuts.
Anyway, I hope the dev keep up with THIS game, since it is a pretty cool one.
