Here are my thoughts as I played:
Spoopy game is spoopy.
I didn't understand you were supposed to not use the mouse right away.
Is it me or is saving not a thing? I'm not a fan of just trying every step over and over again to lengthen the game.
Got the 1st ending in about 15 minutes. I got the correct bookcase, but I don't know how to progress further so I checked the hints. I'm not sure what "in video" means so RIP John. I had a school project about hiding stuff in images, so seeing it in action was cool though.
