It's been a long time since I've played a VN that felt like a shounen battle manga or superhero comic AND was fun, spooky, and interesting on its own terms. This one obviously has a lot of work put into it, and I appreciate that a lot!
And so it's earned the highest praise I can give a erotic game:
"It'd still be good without the erotic stuff."
Please keep refining and working on this one. The bad ends have actually kept me guessing, even if some decisions are actually completely innocuous.
