I wasn't able to finish this one sadly, if it does have an ending, but I like what I played. The lockpickling minigame was fun, and the atmosphere and weather effects are great!
I especially liked the little (big) visual in the distance when the lightning flashed.
Also I think you're missing a collider on the little wooden fence, because I managed to circumnavigate the playable area outside the walls.
Beyond that, I found the quickly draining sanity to be a neat idea since it forced you to move quickly. But a little annoying in that depending on the path the player takes it can lead to multiple restarts just to progress somewhat. I don't think it should be outright removed, but maybe a little fine-tuned post-jam.
Also like the other comments, I'd suggest adding the ability to hold down a button to move, and also add strafing.
But as for the narrative and presentation aspects, this was great! I hope you do expand on it post-jam.
Good work!
