Glad you enjoyed it!
There's a few side quest style things I'd like to add to increase the game's density, the raccoon shack is one of them although I'm not sure exactly as what yet (maybe some kind of treasure hunt?). I also want to make the signpost maze meaningful - my idea is that you'll be able to get an ocarina by completing it and learn a song from the rabbit that will let you warp back to the pond in the village (which is based on Manbo's pond) with a key press. I was going to do something with the dream shrine too, but I kind of like it just being a useless building you can never go in
The witch was one of my favourite characters to write, I especially like their final dialogue which sort of ties in with the mushroom soup!
I was sort of setting up a rivalry between Koko and Bow Bow, so the incident in my head is that they had a fight, but then I only ever gave Koko dialogue referencing Bow Bow so that didn't really get developed! My hope was really that alluding to things like that is a bit of fun and makes the characters feel a little more alive. That's why I wanted changing dialogue and locations for everyone really, so it wasn't just static other than the critical path of the trading quest.
