Final verdict, I couldn't find the tentacle scene or the tied up and duct-taped scene. Just to list some things I have not experienced.
Enemies scattered around like garbage and without any lose sex scene they're just delaying your progress and they're also largely uninteresting.
Losing to other enemies didn't seem to garner me any difference other, no sex scene and I the brothel's repeated scenes wear out their welcome quickly. I've lost to every enemy in the game on purpose, the combat when trying to win is largely boring. I ended up hiring the mercenary to advance the story because, as I said, the combat is not very interesting.
Lastly I found myself switching between skipping through and trying to read every dialog as the story seemed very bland with the character we were playing being a complete dumb ass; meanwhile our other characters were either one note NPC's or a completely untouchable god.
I would not recommend this game for people seeking sexiness, nor good gameplay, nor story.
Oh and you might want to add some dialog that says, "Beating the labyrinth for some reason advances the story."
