I wanted to make a review but I think it's unfair to do so until the game is completed, so I'm gonna point out a few things I like/dislike currently using my very broken English:
-The "build mode" is awesome, I'm guessing it's still being worked on but I really like what I've seen. My biggest "complain" would be the rooms' "capacity"; I know this isn't The Sims, but it would be cool to have the freedom to add and decorate the rooms without having an object limit.
I don't know if it was made to improve performance or maybe to avoid having an "all stats" (luxury, coziness, nature, etc.) room, but I think there's already a "limit" for it with the room space/object placement (rooms are small, you can't put 30 beds/chests/chairs/etc. in one) or just with the lack of money+having to wait for the next day for the trader to restock.
If it's a matter of stats, a "one-stat only" room system could improve the matter, as in "you're only being able to place luxury items in luxury rooms".
-There's also a lack of wall painting and the fact that you can't put decorations in the outer walls of the rooms, but I'm guessing that would change in the future?
-The guests system is also genius, being able to have sex with them after satisfying their needs encourages the player to care more for the mechanic. I saw that there is room (heh) for more future characters, but it would be cool to add more scenes to the current guests, ¿at least 2 more or so? Once you fill the guests' satisfaction meters they just want to rawdog you, I'm more of a foreplay guy so maybe adding 1 scene for fingering/handjob/titjob and one for a blowjob would be great; the game has a somewhat serious lack of blowjobs : p though it's compensated by the fact that each sex scene is unique in their own way.
-I have no complains with the characters, they all feel so real and cute, and their missions are great. The story and worldbuilding uses many common tropes (isekai, war with demon king, lack of male population, generic medieval fantasy races, male protagonist having sex thanks to female insecurities) BUT it feels unique, which speaks marvels about the dev's writing.
