can you share your save maybe with the full gallery ? thanksokay, I have unlocked all avaible sex scene up to v0.21. You guys can use the walkthrough v0.19 to unlock most endings except the secret ending.
For the secret ending, you have to choose scene 1 of Hoofmann route, and the rest of choices choose like route Simon (include winning all minigames in dreams). You will unlock the secret ending. Good luck
P/S: Only take scene 1 of Hoffmann route, don't take scene 2
