Okay, so the art and story is great, humor much appreciated. But damn that guy with the white eyes scared me.
If you're gonna do a spot-the-difference kind of game, I think it's a really good idea if you tell the player what they missed if they say "normal" but there's an anomaly. I gave up trying after 4 runs failed, and each run failed I had no idea what I had missed. Things like the shadow man, cheese, or the hands on the window are easy to spot, but apparently there was some really well hidden object that I just could not find.
Apart from that I think you could improve the door opening/walking animation to make it less obvious that you're just teleporting back, and the kitchen countertop had some annoying Z-fighting.
