Oh, wow! I got teary-eyed at the little guy holding the sock... I remember you saying that you had trouble coming up with the central plot, and it turned out beautifully. Congratulations!
The memory aspect of this is very engaging as well - "This again? I already told you I am the forest!" - made me laugh! It's a great idea to log what paths the player has already travelled down, so you can make slight changes based on what they've already done. I would be interested to see the code that you used to make that happen / how you logged the previous choices that a player makes.
It reminds me of the beginning of Bandersnatch, too - how things change slightly when the main character goes through for the second time, after choosing the "wrong path" where he accepts the position with the company. The slight differences in text can be hard to notice, but are really interesting if you're looking for them!
Your images and visual assets are beautiful, and props to you for adding a custom favicon!
