The plot seems interesting but the MC is infuriatingly dumb in the demo. I'm sure they'll be smarter in the full game (or maybe hope? idk) but the whole thing with the choker was the most obvious thing in the world.
One huge problem though: The pronouns are always female, which made me very confused at first and then very uncomfortable since I'm a man and picked the male option. I also picked the non-binary option afterwards, to see if the pronouns were still female with that one and they were. You should definitely fix that if you want to not make every non-female player extremely uncomfortable when trying the demo.
