OKe, same-face memes aside, I actually just tried out the game, and I must say, this is the best RPGMaker game I've played. I know, these things are usually a pile of shit, but this has some actual quality. The porn aspects are fine, but in the demo there is only a blowjob and a handjob, so it's hard to tell.
A quick note: the degenerate-looking lady has a boyfriend.. And I am not calling out "cuckoldry!" already, I just want to point out that the author didn't automatically think: "Most people like their ladies single, so let's keep her that way".
Also, the ingame riddles don't provide enough clues, so be ready for some trail-and-error solving, if you are going to play.
