for those who want to unlock scenes go to your local disk>Users>(your username)>AppData>LocalLow>Niem2D>Femboy Survival and open the global.json and here you can add the scenes that you don't have, here's the ones that I do have
"galleryData": {
"unlockedScenes": [
"Maeve Blow",
"Morgana Footjob",
"Maeve Doggy",
"Betty Lap Fuck",
"Betty Standing Fuck",
"Vines",
"Maeve Missionary",

"Slime Ass Spread",
"Aqua Riding",
"Betty Facesitting",

I'm not an expert on any of this but I'm 70% sure you can just do this and unlock the gallery as long as you know the name for the scenes, feel free to add your grain of sand or correcting me.
