Really cool world you've got here chockfull of amazing pixel art. Would love to see those enemies in action! I have one nitpick though with the gingerbread house; It feels off due to its black outline and inconsistent scale. As the black outline stands out quite a bit, (just an idea) you could use this to your advantage by having black outlines around sprites to indicate that you can interact with them (houses, enemies, items, npcs, player, etc). That way players will easily be able to distinguish between the environment and important things.
