I tracked 14 different room states across 6 runs and I still can't figure out if the potion in the east tower actually does anything or if it's just a counter that goes up. The castle layout shifts slightly each time, not enough to call it procedural generation, more like the developer got bored placing assets and just nudged things around. You start in some kind of entry hall with chains hanging from the ceiling and a fucking machine already running in the corner, which sets expectations pretty clearly.

The summoners quest framework, if you can call it that, involves clicking on furniture and seeing what happens. A table might trigger a tentacle scene, a rack might start a BDSM sequence with one of the irregulars, those weird shadow creatures that don't have consistent designs between rooms. I spent way too long in the alchemy chamber trying to figure out if mixing potions changed outcomes. It doesn't. Or maybe it does and my spreadsheet is wrong. The Mrs. character shows up randomly, I think she's supposed to be the castle owner, and her dialogue changes based on how many girls you've "processed" through the various devices. The chain mechanics are literally just clicking chains to bind characters to things, no physics or tension systems, which feels like a missed opportunity.

The tentacle orgy room is exactly what it sounds like and honestly the animations there are smoother than anything else in the castle, which tells you where the developer's priorities were. Some rooms have looping scenes that just run forever until you leave, others require specific item combinations that the game never explains. I found a hidden passage behind a bookcase in the library that led to a dungeon with three additional torture devices not listed in any walkthrough I could find. The BDSM elements range from basic restraint to some genuinely intense scenes that made me wonder about the creator's personal life. The fucking machine gets its own dedicated room later on with upgrade options that I still haven't fully unlocked. My completion percentage sits at 73% after all those runs and I'm starting to think the remaining 27% is just bugged content that was never actually implemented.
