I had a ton of fun with this; loved the atmosphere, the overall look was consistent, and the core gameplay involving using the lantern to see the ghosts are a cool way to do it.
Only two tiny issues:
Getting the Tiger(?)'s door open was a little awkward because the item you had to find was difficult for me, and I felt like this lantern drank oil like a fat kid drinks diet coke.
I'd love to see a full game based on this. Solid 9/10 job here developers and I hope you keep making games, you have a great understanding of fundamentals here!
