Beautiful game, I can see the inspiration on Junji Ito here, you did great on the shading, scene building and ambiance in general.

The story is simple, easy to follow, but... It doesn't make much sense you know. He has to turn the lights off and all, but then that... thing appears and he says nothing? I would expect him say he's so tired he's seeing things, but nope. I don't wanna stay here all day, so let's say there's less dialogue here than I was hoping, considering it's inspired by the master.

I can't say much about gameplay, it's simple and it works. Nothing new or that stands out. I really did like how you inverted the mouse in that part though lol.

The graphics are definitely what makes this game stand out so fricking much. This shading really made the Junji Ito style flow out of it so much better. Really hope you make a game on this style that is more bigger by the way. xD

I think my biggest negative feedback for this is how short it is lol. Other than that, this game is beautiful, great job! :p
