I didn't cheat on Celeste and didn't do anything lewd with others. I only communicated with her, except for a few moments when she didn't want to or couldn't communicate. I haven't come across a single NTR scene! There were some hints, but it's most likely that the plot has one basis, it was simply conceived that way, even when there was a scene where she was supposedly in the room, representing relief to all the monsters, she was simply listening to their prayers.
There was a moment in the plot when she suggested an open relationship, but Persival can choose the option to think about it and she remains faithful to him until the end.
But in the Straight Path there is not a single full-screen sex scene with her. The first lewd scene is a kiss scene, the second is a strange sex position.
One "gay" scene was when Ryan invited Percival to the men's bathhouse and there was a brute and a minotaur, they just talking about size differences and thats all.
But what killed me was that at the end, when Percival wants to run away with Celeste, they have an auto-fight with Ryan.
They win the first fight, but when the bartender transforms into Super Ryan they lose. Percival dies. The ending shows Super Ryan sitting on the throne with his dick naked and at his feet Celeste, the Witch, and the Red Imp, they became his whores. WTF? It's a joke?
I play the whole story in the Straight Path and this is the outcome! Lol
Most likely, in order to follow the NTR path, Percival must donate sperm to a witch at the very beginning and lie about it to Celeste.
Why aren't there any hints in the game like the ones in the menu with the magnifying glass, about the characters' secrets (letters) and their favorite foods? Is this an unfinished-completed version, or are there bugs as usual?
