I played the game for a couple of hours.
It is clear that dev put a lot of work in it : music is really nice, characters are gorgeous, even males characters are nice (and we all know that it is pretty hard to create nice male characters with Illusion games).
I really liked the writing too.
If I may, I would like to suggest some QoL improvements :
Add a "General Market" button in Locations when you are in the Office. It should save some clicks (actually, in order to go to the Market, you have to click on "City Map" then "Shops" then General Store).
Add an "Office" button in the General Store window and the Red Petal building management. Again, it should save some clicks.
Remove the "Management" button in the Office. Management menu could be accessible while clicking on the Girls portraits at the top.
In "Management" window, display the bonus to General Skills (given by improvements and talents) for the Girls.
In "Management" window, in "Biography", add a list of gifts liked by the Girls, when MC has chosen the right gift.
When clicking on "End Day", add a warning if there are still AP available for sex training. I missed the fact that you could sex train the Girls during daytime... I thought you could not combine sex training and others activities.
For General Skill training (or Sex training), add a bonus if multiple Girls train the same Skill ?
Add a feature to auto-buy some stuff when it goes under some values : for example, auto buy food when there is less than 2 food. Or auto-buy gifts for Oirans when they are available at the Store. This feature could be an unlock, tied to your reputation.
And I spotted two typos :
In "Management" window, "Overview" tab. The tooltip for "Auto-Rest" has two typos :
"Set Oiran to rest automaticly (automatically) once (...) are bellow (below) 50%"
Congrats on that game, i really love the aesthetics of it. Can't wait enough for the next version
