For a game that has NTR in the name, this sure doesn't feel like it actually has any NTR.
I mean, sure, the girl gets fucked by a bunch of randoms because of altered morals induced by hypnosis... However, both she and her friend forget that anything unusual happened when they're out of the dungeon and at the end as well. The girl is not affected by her experiences in any way whatsoever, and neither is her childhood friend. The two aren't in a relationship either.
So I dunno... Can't imagine that any netorare fans would actually care for this one.
All in all, lazy shovelware, which I believe is pretty typical of Maze of all circles. Not the worst way to waste an hour or two, depending on how much time you take to enjoy the rather short H-scenes. Can't hide the text box tho, which is complete ass.
