Finally got around to trying it. It is a charming exploration. I have found the sexy bits a bit too in your face too fast, such as window peek at the game start, since I only like it with build up. It also doesn't help that tiny pixels don't hit the feelgood brain chemistry as well as high fi visuals of butts would be, so I wasn't playing it for the sexy.
But I do love the parody, the humor and all the character play and immature puns, those are very yes. Very yes. Sexy funny is the good mix in dialogue. Setsune one was the fun one. Honestly, the parts where the dialogue was going full in without any 'self-awareness shyness' were the good ones.
Also graphics are very nice as well for solo. Music is mighty even if a dat modern generic.
But with all the charm, I did get tired of all the exposition, as I was going through the content. I can see a lot of effort being put into the room, but it does get a bit old to read every furniture square and all the talk.
I think it would have been better off if the content present was instead revealed up over an overarching plot of few days, a hotel story to think and solve or just some overaching structure to pace you along. I think it would have been easier to make too, because what you currently have looks too overwhelming for solo hobby, all the rooms with low-key promise of changes over few days.
