Just finished it yesterday, what a lovely little game! It was a delight to play and I loved how well crafted the environment and the characters are. I loved it so much, I'm translating the script in Italian just right now :)
If I had to add something it would be probably a map or quest list (as someone else suggested elsewhere) to check if I have explored everything - maybe to unlock after you finish the game?
I'm going back to play nevertheless, 'cause this game is too precious.
