Thank you for the game - it's got a chill athmosphere. I was thinking it would be spooky, creepy or scary but I don't think it is (well, I did not manage to progress much so I might be wrong).
A couple of notes from me:
About going foward and going back - if I go foward and enter the new corridor, then turn around and check the door it says go forward again. It can be confusing because it is constant rather than relative. Maybe it would be more clear to name them "Closer" and "Further" to the targer room. Or maybe that would be confusing as well? Ah, maybe it's because the doors as a mechanic combines two things - movement and assertion. If they are separate it would be a more streamlined experience. Like pausing the game or entering a special mode to input if the player believes there is an anomaly.
The notification "You missed something" appears whenever a mistake is made. But the mistake may be false positive - thinking that there is an anomaly when there isn't. In that case it's not missed but imagined. Maybe it would be more clear to add - "Your observation did not match" or something like that.
Good luck!
