For your first demo, this is stellar! Good work!
Oh is that it? It felt like it wasn't working at all.
The audio itself was what's uncanny. I found the writing to be fine. Did you machine generate it? It doesn't sound like a human did it.
I did find some of the info in the pause menu, but it really sucks dying when you have no idea why. I understand why you'd want to be more Souls-like, but in Souls, you generally always understand why you have died. I assumed that guy was immune to the flashes but I figured it must be that so I kept doing it. If you insist on it being that small, its actual hitbox needs to be pretty clear somehow. Like a spherical aura around you, not just light.
