Played this with my husband just for fun, wanted a semi-quick escape the room experience before bed. It definitely challenged us to think, which I really enjoyed - made solving puzzles more satisfying, but we were left confused as there were several elements & puzzles in the game that had no purpose other than to just to mislead / misdirect the player (Unless we seriously missed some stuff!) I don't mind a little pointless document here or there but these seemed like full on puzzles we worked hard to solve and... could do nothing with. Anyway, we beat it on the first try with 9 seconds to go.
Difficulty level (including the red herrings that irritated the hell out of us): 6
Frustration level maximum: 9
Still, would like to see what the developer does next! Less red herrings please!
