What sets this game apart from your average itch.io horror experience is that it actually tries to paint an earnest picture of a place where something extraordinary happened, as opposed to lazily showing us a world where everything exists solely to justify the inevitable jumpscare. It's folk horror to its core, rooted in the traditions of the people from the town of Thunderhead.
And tradition is all they have to try and make sense of a violent, fast-evolving phenomena they have absolutely no chance of understanding before it consumes them (it reminded me of a certain short story by Lovecraft). The whiplash ending puts us in the same mindset they probably had in their last moments: incredulity, with a nice dose of despair.
Overall a great experience, and I'm impressed the developer managed to pack such concepts in such a short game.
