Not bad at all!
I've seen people criticizing the MC for being weak, but it fits the story better that way, also of course people are nuts at anything NTR related. I'm not a fan and don't actively search for it, but when you have a sex demon and a "landlady" in need to do whatever she can to keep the job I think it fits greatly.
Graphics and animations are great, character models are hot, even if I'm not a fan of disproportioned body like the milf of these games, the schoolgirls look more interesting. The writing is better than average, definitely, and conversations flow nicely enough. Music is well implemented IMO. The lack of rollback is not funny, and there are some weird takes on the police (giving away details of a murder scene to the protagonist way too lightly, but not only that) and curious choice of outfit and purse accessories from someone coming by to cook dinner (beside the fact that an 18 yo needs someone who cooks for him when mom/landlady's away..) which were too much porn logic in an otherwise pretty consistent story so far...
Anyway keep up the good work
