Congratulations on completing the project! Obviously, this deserves praise on its own, since it's a rare thing, but let's face it, a complete but crappy game would still be pointless - luckily this is not it. I had good fun throughout, the visuals are always nice, the gameplay never got obnoxious. I'd certainly not mind playing a game with a similar makeup as this one again.
As far as my critiques go; the "cave arc" imo was the weakest, in some of the sex scenes the writing nosedived into some sort of porn parody dialogue (at least in my opinion) and overall I'd wanted a somewhat stronger "survival" element, but then I imagine lots of people rather would have wanted less gameplay ...
Not much else to say. Good luck with the Steam release, assuming that's happening?
