Does anyone know how to use "cheat engine" for this??
No. But you can cheat money, lust or favor with savegames via save editor online dot com.
Any way to manage stamina? The sex scene always ends without even climaxing smh
ASFAIK sadly no, its a pretty bad game design/mechanic, but the game has tons of bugs. One is that using anal beads dont consume stamina, but increase climax, use that. Rotors are useless, they do nothing, but expensive. Masturbating is pointless....
Pretty much unfinished game if you ask me
, but fun for the first 40 minutes.
