Couple little qol things:
any chance you could make it so the player can nacigate menus with just keyboard, swapping between both hands on keyboard to the mouse doesn't feel very intuative.
having a way to customize controls would be nice since I'd prefer to have the action buttons be in a straight line Instead of being bunched up like an arcade button set up. (Most players would probably prefer WASD and being able to do actions like the light, inventory and anything else with mouse and space or even just arrow keys and ZXC and space for actions.)
Having some sort of explanation to the girls mechanics be front and center instead of just looking like another wall of text would probably help cause most players aren't going to read the instruction if it's a wall of text. (Example: give the player a map of the area they can open whenever they want and show a picture of what the player needs to interact with and how to interact with it, picture of fremy's box with a picture of the interact key that says hold on it, etc.)
Can't think of anything else in particular to advise other than these and that each character should be introduced each night instead of all at once just so the player has a chance to get used to each mechanic and can learn how long each girl can be ignored.
