Steam review snapshots
The atmosphere is well built, and the game does a good job pulling you in at first, though the lack of depth…But not all rooms behave this way, which makes the layout feel inconsistent and surprisingly confusing.It is a point-and-click adventure game with a psychological horror atmosphere.Instead, it traps you in a psychological spiral, where mystery and fear slowly blend into fascination.Why it fits
Check it if you want adventure filtered by weird, single-player.
