Nice work on this, Echo. Beautiful imagery, and I like how this connects to classic Haiku thems like nature and spring.
I like the table at the beginning, with just diagonal lines -> the question of, "what am I looking at here?" And then when you click forward, you start to understand what you are seeing. Much how many poems unfold. The most striking moment for me is probably the moment when the book opens, and you start to understand more what you are looking at -> seeing familiar things in a new way.
A question to think about: is there any way that you could make this game slightly non-linear, so that there are multiple options or pathways for the player to encounter? How do you think that would affect the experience?
