Wonderful and atmospheric game that mixes puzzles and manages to prevent a 'walking simulator' feeling.
Puzzles felt satisfying, and solving the secret code was quite satifying.
My only complaint is optimization - the game was barely playable in some areas (I'm looking at that house with the drop-down hole to reveal). The game ran at around 5FPS. Otherwise, a fantastic experience lasting around 2 hours.
Highly recommend a playthough.
