Hi! Thank you for playing and leaving feedback, it’s much appreciated.
Figuring out the Mothman mechanics is a key part of the gameplay (though it’s our fault for not making that clearer).
As a tip: The game heavily relies on audio cues (the specifics for which are detailed in the book) and matching sounds to rooms. Also the book includes several other hints beyond that on how mothman behaves.
Let me know if you decide to play again and have some trouble still, i’d be happy to help out :)
