i love this aesthetic. it's so round and chunk! it's also very clear in terms of gameplay
i was trying to think of suggestions that would 1, would fit in, 2, i haven't seen much of. tossing out... moles or prairie dogs to pop out and look around; same house roof except there's green things growing on it; more ladders (i really like your fences and ladders) i'd love to see a wobbly ladder-bridge that might break for some puzzle fun. i was also reading about a Native American technique of digging a vented hole, building a fire in the hole and the smoke comes out where the vent-tunnel exits ... so like smoke and fire separate. there are seriously dozens of campfire sprites and that would set you apart. and also not burn down the meadow!
hmm. you'll probably want nests and haybales/stacks at some point. Beehives?
and as usual i am a big advocate for water, wells, and buckets.
