Cute platformer, cool graphics, and interesting main mechanics.
Quick tip: Your game is freezing whenever a new particle appears (e.g., blood, jump particles, etc.). This is a known Godot issue that's already being fixed in the latest versions, but there's a trick to solve it now. Just place all these particles in an opening scene (it can be behind other objects/interfaces).
Back to the game, I liked the way you made the spider move, and the way to kill the creatures is very intuitive.
Congratulations on the entry!
