Good atmosphere but puzzles need work
I enjoyed the horror part of the game. Some might think the jumpscares are a bit cheap but most people have become so jaded over the years that its pretty much the only way to keep me them on edge.
The puzzles really need some additional going through though. There is too much pixelhunting in dark enviroments and some item are needlessly unobtainable until the game dictates otherwise. The latter wouldn't be so bad if you could atleast interact with the items initially but as is the player will disregard them as part of the background.
I also think two of the puzzles actually have errors in them. Unless some form of bizarro maths were used the third and fourth digits of the "correct" safecode should be switched. Also the text your supposed to reference in a puzzle doesn't have an eight row, though that one shouldn't get the player stuck atleast.
Finally puzzles that require a lenghty redo if failed preferably shouldn't include trial and error elements. Though I guess its possible that I missed some reference to symbols earlier in the game.
