Finished it. To open doors for every girl you need their curses. Nurse's and gray/deamon lady at 2 floor, werewolf 1 floor, Bigtitty frankenstein in the undenground. To get to undenground you need to find a key behind one of paintings at 2 floor, then smash doors with curse from frankenstein, then you'll need a blessing from elves that you get by entering one of the rooms at 1 or second floor. To enter werewolf chamber you need a date from painting at 2 floor. After entering nurse's room you pick a note from the floor and go on 1 floor, then you need to find a doors and set colors to races of the girls and painting frames from the room nerby. Last girl, gray skinned one have a room where you need to set moans in certain order. Theres a paper on the wall describing color of the skin of girls at the paintings, and thats the right order. There's also one room with a short story that also need a correct order - Tavern, Market, beach, forest tavern don't remember what is it needed to, but someone might find it usefull.
