Thank you so much for taking the time to do a let's play and a review! As far as the creepypasta game jam thing goes, you're right-it's just mentioned on a splash screen at the start of the game, not on the website. Though I should mention that it's inspired atmospherically by creepypastas, but the story and characters are original.
I'm glad it was an immersive experience for you! Thanks again for the detailed review, and I'll have to check out those recommendations!
