I commented on the game itself too but I just wanted to say I love this. A lot of other submissions have good mechanics and art, but don't have a clear goal or ending or story - you know, a game. This one is a complete experience and I really appreciate that and I think the art style and everything about the presentation are consistent and just great!
I would like to be able to see the ghosts from a little further away - some of the jumps felt like pure luck, and the physics are a tad floaty for my taste, but that's just personal preference.
I really enjoy the story - it reminds me of a Lovecraft story for more reasons than one. The "twist" ending is obvious to the player long before it becomes clear to the character, just like Lovecraft, and the reveal in the mirror at the end reminds me of The Outsider.
Awesome awesome job all around!
