I am so obsessed with this that it's hard to even express, but I'll try to be articulate for the sake of a comment.
First of all, fantastic use of physical space, I have been trying to wrap my head around my own ideas for games that take place in physical space, and I think you nailed it.
Secondly, you've written fantastic instructions that are fun, clear, concise, and easy to read. Not only do I feel the urge to go out and play this game right now, it feels like that is extremely achievable. (I particularly appreciate your use of bold and italics to cue/prompt the player within the text. Really user friendly to me.)
Thirdly, everything about the actual gameplay is adorable and intriguing. The prompts are open-ended enough that I can imagine myself into them, and I think the prompt to consider the italics is a really fun and simple way to guide deeper thoughts.
I crave an expansion with MORE woodland scenarios for my mushroom person to deliver!!
