Right so the neighbor girl in Holio Dorm, she's got that whole gothic thing going on. Black hair, pale skin, probably listens to Type O Negative unironically. The setup is you pretend to be into magic and metal to get in her pants. Classic. The minigame where you actually seduce her though, it's basically a rhythm thing but not really, more like tapping at the right moment while she gives you this look that says "I might curse your bloodline or drain your balls, who knows."
The pickup dialogue options are hilariously blunt. You can literally just go "nice boots, wanna fuck" energy and sometimes it works. Other times she calls you a poser and the minigame resets. I spent way too long on one part where you have to match some symbols, it's like a memory game but horny. My fat thumbs kept missing the last one and I'm sitting there getting soft while this pixel goth girl stares at me disappointed.
What's weird is the blood thing from the description. It says she'll make you cum with blood? That doesn't actually happen in the version I played unless I missed a secret ending or something. There's some red visual effects during the climax scene but it's more like a cheap filter than actual sanguine fluids. The sound design is just a looping metal riff that gets annoying fast, had to mute it and put on my own playlist. Honestly for a browser game the animations are jank but the brunette's expressions during the seduce parts, when she bites her lip, that specific frame lives rent free in my head. Wish there was more buildup before the hardcore stuff but whatever, it's a quick fap game not a visual novel.
