Piss me off.....
In a good way, 9/10 - No Memes, No 10/10
On a serious note, interesting take on the theme. First time playing a game with the unique mix of scoping out and really taking your time playing through the levels which is what some games are lacking nowadays.
Some suggestions I think may or may not be better for the game:
1) It could use a neat little option for players to enable checkpoints/restarting at the same level for those who wants to have an easier time.
2) Add some jump scares if you are really intending to go for a horror game.
3) Co-op: Added player to help guide main player while main player's visibility is much more limited.
So in all honesty, overall game rating for me is 4.5/5.
