First of all, thank you for playing!
Red bar is tireness, she need rest, most of the time when this bar is pretty low, they just ignore you and go to sleep, also, if you have not giving them enough food, as soon as you touch them, they inmediately go to the kitchen (unless there are 2 characters in there) Of all of these the most dangerous is hunger, if you keep them starving, they leave the building and never return.
The other icons in the rooms are for manteniance mainly: take out trash, washing dishes, washing their clothes, repairs, cleaning.
If you don't attend to the building's needs then there will be complains from the girls and soon or later you will be kicked out the building.
For the special scenes and peep. Well I really wanted to add some spicier scenes mainly at night but also on the bathroom and kitchen, depending on the level you have with the girls, unfortunately time reaches me and I could not add them, those scenes still will be pixel art, but in a 2x zoom.
