In my irrelevant and personal opinion the developer brought this on himself; he stopped releasing the public version without exlplain why, crack versions don't work unless you do things no one tells you to do, each version brings less content than the previous one, he wastes too much time on anti-piracy methods instead of focusing on developing his game, he abuses cliffhangers, he went to work on two other projects without finishing this first one and there's other things I won't mention, all while still charging $15 for immediate access to the poor content he releases, come now.
And what quality are you talking about? Only the art is good, the story is lousy, the sex scenes could be much better and the dialogues couldn't be more cliché, for me it has the same regular quality as all the "good" NTR games, if you are looking for real quality Elf's NTR games will surprise you.
In the world of hentai games you can't do that and expect people not to get upset, I fully understand that the guy has to make money from all this, but it's clear he bit off more than he could chew, I used to support him on his patreon, but stopped when I noticed the path he was heading down, I felt like I was stupidly throwing my money at him every month for nothing, now I'm just waiting patiently for the release of the full game which was supposed to be in December but I doubt that will be the case.
I respect those who love this game and defend Fallen Eros, they have their reasons for doing so and I sympathize, but I wont support this developer monetarily again, I don't like what he has been doing recently.
