How are you guys hava hard time with this game holy hell?
Just play Easy mode AND FOLLOW THE DAMN GUIDE! I had no problems following it at all.
Some spoilers for the endings
"Love ending" is the "NTR" Ending (if you stretch it enough), but more on the girls being more on Femdom humiliation by Jealousy of not being able to fuck them. Then you get femdomed by a Giant Monster Girl and says you're special even among Virgins because you're also a Masochistic Cucklord...
"Slave" ending is where you have sex with the girl you choose, while you get striped out of your identity and becomes an another nameless sex slave for them to milk.
Escape Ending is where well, you escape successfully, but in the True Escape End You got so enamored by the women that after they returned the car you left behind, you returned back to the village to be their slave anyway
It is a FEMDOM focused game of the "Cult controlled by a Monster" Variant, which is quite rare especially nowadays.
