Agree with pretty much everything that's been mentioned here!
Game feels very charming but could use better controls and some polish here and there.
Also: for the burrows, you're using one scene that spawns the player from the left hand side, no matter if, in the overworld, the player entered the burrow from the left or right, therefore breaking the illusion. Consider checking the origin on a variable and then spawning the player entrance in the burrow scene based on that variable :)
