This game is so atmospheric, I love it! I feel like I could play this for a while if there was a bit more to the gameplay.
Speaking of gameplay, while I don't mind the amount of spikes, I feel as though their hitboxes are a little unfair. I'd have their hitbox lie a bit further in from the edges, just so that a player isn't punished for lightly grazing them. One pixel crossing into the spikes shouldn't be a loss!
Other than that though, really nice entry!
