Awesome entry. The worldbuilding, art, and atmosphere work together really well, along with the public domain assets you used (love me some Chopin nocturnes).
The game is obviously short and not "complete," but there's definitely the glimmer of a full game in there, and I would love to play an expanded and fleshed out version of this.
The pixel art is phenomenal. It does get a little jarring with the very low-resolution images in the introduction, but obviously there was only a month in the jam and you made an enormous number of assets.
Excellent work!
