I got interested in this project since the screenshots on the WIP channel.
First of all let me preface this is my opinion solely as a player and not a developer, as this jam was my first finished project.
I think the art design and atmosphere are a real gem, really unique and dare I say on the level of Indie games such as Limbo and Little Nightmares (with its own unique approach).
Unfortunately the game design and coding aspects aren't on par, got stuck a few times, both for lack of handholding (didn't realize you could vault) and actual bugs (both minor such as player Z position not resetting on respawn, and major bugs as when after freeing the monster thingy i got frame dropped to 1 fps and couldn't finish the game D: ).
Seeing as this was a solo dev project this is really promising, I think if you got someone to help you out with the weaker parts of this game it would turn out great.
Definitely my favorite submission on the Jam, much love!
