This game feels special, I think primarily because the story aspect of it. If I had to categorize it under a genre, I would say walking sim (with some added mechanics of course), but even as a walking sim I felt engaged throughout. I appreciated that you didn't tell the player how to survive or how to play the game (outside of the controls). Instead, you let the player figure it out on their own, and that adds so much to the game. I do wish that the controls were presented as button prompts or text boxes that faded in while you were playing the game, and then faded away, rather than being a text on the main menu.
I think you were going for something cute, yet spooky and a bit atmospheric here. I think you could focus on making it even more spooky and atmospheric, with darker visuals, darker music, etc. Also, the lights were great, but it might be cool to make some of those moving lights come from some kind of shadow monsters or something, for that extra spooky factor.
