Allow me to smack my two cents (wall of text, rather) on the whole hate-train for the v0.16.
I've tried the new version, which is more of deckbuilder and VN combination, to see what's left last pages here in such disarray.
It's... not bad. From what I gather, it is currently more of a proof of rework, a build that confirms that he didn't do fuck all the whole time. Which means it's currently super short and empty. Most of the content that was available in previous versions isn't there yet.
Of course, that didn't look good to me too. I've checked the trello, that someone here mentioned he has, and from what I see, the Karryn's Prison's corruption/fetish system will be back with all the related sexy stuff.
I understand that game going from LISA-like Sidescroller RPG, to Sidescroller deck-builder, and then to unusual (at least for me) amalgamation of VN, deckbuilder and some RPG elements on top is weird, and that's not mentioning how one update was scrapped. Several months of waiting for this update didn't help for the dev's image too. From what I've seen, his response wasn't exactly professional to the whole bashing from f95 community. And some people donated for a specific game that is an entirely different one now.
Heck, I, myself, am so sick of seeing boring copypaste RenPy VNs so much, that I just avoid them without even giving them a chance, however bad that sounds.
However, my point is:
As far as I see it, sidescroller RPG wasn't the cornerstone of this game (or at least not solely), but rather the art, setting, and the corruption/fetishes, that you could choose, mix and match to your own liking, to complete the game how your dick sees fit.
Again, it seems like the corruption and fetishes will still be there, at least according to trello on v0.17. Art and the setting are there as well. Deckbuilding gameplay (that mostly went uncriticized, and definitely not as harshly when it was first implemented) will probably be akin to v0.15.
Considering the amount of comparisons drawn between KP and Saria (rightfully so), I am pretty sure that it's the corruption of specific body parts that was one of the (if not the) main appeals, and again (I'm reiterating that for the third time now, please excuse), it seems it will be back.
So, all in all, those who specifically wanted a sidescroller, it seems like you can jump the ship at this point. Those who have specifically donated for a sidescroller game... yeah, that's a very bad sight. Sorry that happened to you peeps. Your anger is understandable.
Developer acted unprofessionally, despite changing the game to this extent (getting donations for one type of game, and then changing it multiple times to something different is obviously gonna be disliked). Though at the same time, receiving this kind of community response would've brought the worst out of any person, methinks.
My verdict? I'd wait for the v0.17.
If it sucks, has weird genre-changing shenanigans or alike, I guess hate-train is justified (though I still feel like some gone overboard).
If the content/systems are back and the game just works - I'd stick around for the game and watch how it goes.
P.S: please no "dev 2nd account" or "paid shill". I just felt like both sides have wronged in some aspects, and wanted to mediate this way.
Cheers.
