This was delightful (and also infuriating, in a good way!) to play. During the game, there were so many trees, and I would just like to suggest to maybe add an index/collection of all the trees you've fallen victim to add a bit more of a completionist aspect to the game that isn't just the hat and the coins.
Edit: I've watched some videos on the game. Seems like I missed those signs at the beginning, like many others. Maybe add some indication on unread signs, like a yellow bouncing arrow above it?
