Look I get you tried to get a SH feel out of this but it falls pretty flat for a few reasons, and those few reasons also lead to bad game design choices.
For example, when you get the red key you lose the bobby pin, which removes the chance to go back there until it shows up in your inventory, this feel less fun and more like your a DM railroading me rather then me exploring. The enemies are all pointless you can easily skip them with out ever shooting them, I suggest you remove the arrows to give the damn things a point.
Enemies respawn in the same place, even when it feels stupid for them to. Look I shot the dog, let it stay dog, spawn one on some different screen rather then in the same place after I leave, it just make trekking back more of me clicking the arrow faster to rather then me looking at your Okay artwork.
Now the few things I like.
The intro was okay, better then most flash horror games that don't try.
The puzzles wasn't complete bullshit, which is refreshing for a change.
The okay artwork you draw is nice to look at and feels like you put some effort into it.
Lastly the ending I want to say.
Wasn't shocking or anything, but felt more tact on.
a 2/5 or a 4/10 if you like the old scale.
