Review is for the patched version of the game only.

I bought this on sale because the reviews made it sound pretty novel. I agree. This is a good erotic horror game that elevates the rather tired trope of the anime style succubus into something legitimately scary. While I don't really like puzzle games this one is well done and I've enjoyed collecting bad ends while I played it. I would recommend this game if it's on sale, with a few major caveats:

1: 1 of the 3 succubi caters extremely to... ahem... "Japanese otaku tastes". Now I've been an anime fan for more than 30 years. I've seen things you people wouldn't believe, so it didn't really phase me but if you are at all "normal", easily offended, or don't know what I mean by that, you might wanna skip it.

2: after I played almost to the end, and was pretty sure I was gonna lose I looked at the guide, and wow is the method of getting a good end convoluted... even compared to old sierra games. I will not bother trying as I have enjoyed the unhappy trajectory my character took and where he's ending up.

So, yeah... as I said... great atmosphere and use of "sexual horror". Worth the modest price for the time I played.
