i finished it and it was really interesting!! a little tricky but not hard enough to need to look up, just thought it was really clever when i did figure out the puzzles :D
the first time the game closed on its own it startled me a bit but it wasn't /scary/ per se, i just didn't know when to expect it the first time, i think the scariest part was the shift in atmosphere when i first turned off the lights haha (i'm not really personally creeped out when a game involves interacting with files on the computer but i do think it's a clever gimmick to implement ^_^)
