TL;DR: High quality but generic art, fun gameplay that you need to probably pick a higher difficulty to have any challenge, very tame with minimal extreme fetishes, simple story, and likable monster girls. Definitely one of my favorite games on this site.
Gameplay: It’s a fun time and if you don’t look at what clients you have, then you have to make more calculated risks to hopefully get the right client. If you look ahead at your clientele then that’s smarter, but the self imposed challenge is quite fun. The new game plus mode is cool, but I only used it for earning the achievements which unlock benefits such as new monsters, income bonuses, and overall things to make the game easier.
Art: It’s very nice, if not a little tame. I’m okay with that since I’m pretty vanilla except for mild ryona which the mummy fulfills in being a masochist. She's irritating at the start, but she begins to like the player after a little while (and the game forcing the player to be kind afterwards is nice because I always enjoy the affection routes of H games.) It is why the mummy is my favorite despite literally being a normal person with bandages on them but that’s what I mean by tame. Each girl is largely human except for the bare minimum to count them as a monster. The werewolf is not so much a werewolf and more of a girl with wolf ears. She’s cute and all, but still, minimal.
Story: It’s a tad weak. Very simple and linear, but that doesn’t hurt the experience in my opinion. It throws you into the job of brothel owner and forces you to pay a fee after each week. You learn a little more about your debt collector after each week through cutscenes and eventually face a final challenge if you want to help her out more than just what you owe. I couldn't find myself to care about her, but it was passable. It's not like the protagonist or Death was very unlikable.
Monster Girls: It’s highlight though, is that it shines in the variety. Most of the monsters have varied personalities. Some are feisty, others are stoic, and they’re overall sweet when you increase your affection. The ending scenes are a nice touch, but some of them feel out of the blue. I feel like the spider should’ve had the Minotaur’s ending, but most of them end satisfyingly.
