Hello there and a Happy Halloween.
I played your game as part of a massive scary games compilation for Halloween (you can find the time code for your game specifically in the description), and I gotta say I love the idea and the style of it. And I like to think it's a huge compliment that I actually thought you had made a much more complicated puzzle than you did when it came to the locked chest, heh!
Very cool idea. Gave me some Eternal Darkness vibes.
