The ranking system is broken and I hate it but I keep replaying anyway. You're this priestess with massive tits, brunette, walking into a mansion full of cursed souls. Six of them. The game tracks your rank somehow, I still don't fully get the math behind it, and that determines which ending you unlock. First time through I got the worst possible outcome and the ghost girl just laughed at me. Not even a sex scene, just mockery. I almost closed the tab.
But the animations. When you actually unlock them, they're proper hentai sequences. The asian ghost girl with the long black hair, her body sort of flickers between solid and translucent while she's riding you. There's this one scene where she's on top and her breasts bounce with this weird delayed motion because she's not fully corporeal. It's hot in a way that doesn't make logical sense. The priestess character you play as, she's got this serious expression most of the time but during the animated bits her face completely changes. Mouth open, eyes rolled back. The contrast is jarring.
The choices feel arbitrary sometimes. Pick the left door instead of right, suddenly your rank drops and you've locked yourself out of content. I wish the game explained literally anything about how the scoring works. The mystical atmosphere is decent though, the mansion has these floating lanterns and the ghost girl appears in mirrors before you actually meet her. Creepy but also I'm trying to fuck her so the tension is weird. The priestess outfit is ridiculous, those robes can barely contain anything, but that's the genre I guess. One ending I got involved her becoming a spirit herself, which I think was supposed to be bad but the animation that played was the best one. So was it really a fail state? The game says yes but my dick disagrees.
