[Rev @ v0.2b]
I think this one needs to stay in the cooker for a revision or two.
Art's another 'meh' rendition of renderer software + RPGMaker RTP.
Writing is very rough. While it isn't machine translation levels of terrible, there're already a few lost-in-translation moments in the dialog, and even UI text like the RPGMaker character classes and whatnot. Voice is primitive and, fluency is rocky and characterization is threadbare. I've played around half a dozen Japanese games with this same or similar enough premises with the only difference being those other games have better pacing for the corruption/NTR. This is one of those "guy turns his back for 5 seconds and his previously devoted vanilla wife is magically a superkinky slut".
Nothing I saw in the porn bothered me, but that's because a) everything I saw was vanilla as hell, b) everything I saw I'd seen in approximately every other porn game ever to exist, and c) there really wasn't much in here to see.
TLDR: Premise has potential, needs further development and more work to realize it. Good luck.
