Finally got to playing this one. It's rough around the edges, but it's explicitly marked as a prototype, so that wasn't unexpected.
I like the idea of the story, but it dumps way too much lore way too fast. It falls into the fantasy worldbuilding trap of heaping a ton of capital letters in-universe terms on me all at once, and none of them mean anything to me. Less is more here, we don't need everything up front.
Like I said, I do like the concept of the story, and I like how things are revealed to you as you advance. The image of the Mother slowly revealing itself was a simple, but neat trick.
The gameplay I'm not sold on. Auto-targeting means you're basically just hammering the mouse button and avoiding enemies, which is pretty dull. Maybe more things could be added to change things up. Judging by the (debug?) buttons in the corner, it looks like more was planned.
I think this might have received more attention if the game page showed some screenshots and talked about the gameplay more, but it's two months too late for that.
