Someone may have already written about this, but if not, it's worth mentioning that there's a bug in the game--> James shows Dia a picture of her failing to kick a thug's ass on the subway, but Dia actually kicked his ass (Selfless Dom route). And the version of the photo James shows (accompanied by his criticism of Dia) apparently refers to the "Selfish route" . Why "apparently" - because I'm still going through the game for the first time and going the "Selfless" path. I hope the author fixes this. Also, somewhere early in the game one of the renders went missing (can't remember where), but also on the Selfless dom route.
Considering I liked Luna's Fall from Grace a lot, I hope Diatima's Isekai turns out to be just as good. As for the sandbox elements, they don't really annoy me (not a problem for those who played Fashion Business, ha-ha), but I would simplify some of the interface elements. Say, I'd make it more intuitive to quickly move around the apartment and around the city. Sooner or later all this mouse-clicking will get tiresome.
Overall I like the game so far. The MC is just adorable, hopefully one day she'll meet Raven and together they'll kick the asses of all the remaining scum. I'll be keeping an eye on the game, it's definitely intriguing, though that intrigue may not be as obvious to those players who have played LFFG before.
