I played through the game though I'm confused as to the purpose of the 2nd floor unless it's still (W.I.P).
In the basement I managed to get the (I presume 3 scenes: Blowjob, Missionary(on bed), Table sex) scenes with the blue girl.
I got the headless girl on the table that pulls you in.
I got the nurse to catch me but no matter where I hid, it seems that she only pulls you out and has only one cowgirl sex scene.
In the basement I managed to finish everything, get the 3 gun pieces which stalls the 2 girls for 3 minutes, the crowbar, the valve to stop the fire and the fuse for the electricity for the 2nd floor...
On the 2nd floor I'm stuck since I don't know what it's purpose is besides having sex with the nurse. Since I tried interacting with a lot of things, found the shed but there's nothing in that general area. And for majority of the 2nd floor besides hiding spots.
Also in the basement there's a door leading to somewhere in that bedroom place with the wardrobe (Assuming that's a W.I.P zone). But if anyone has more info on what to do... do tell, ty~
