I agreed with Spook and Champpeace, the combat mechanic is not very good, you can only swing the sword when the goblin is in range is weird, people usually would try to swing the weapon to get the feels first, but if they found out that attack button doesn't work they will get confuse.
You could change the music theme when enter the game and the afterlife scene to get more out of it.
Also, It would be great if you learn the rule tile, I don't know what it's called in Godot or if it's exist, but if it's exist please learn that, if it's not, try to make the map look better and not discontinued tiles.
