This game was super ambitious for a game jam, and from what I saw of it you did an amazing job! The story was captivating and made me want to keep playing. I did find the pace quite slow as it was mostly walking between nodes and looking for objects, and I eventually stopped playing when I got overwhelmed with the options. I see there's a cheat sheet in the comments so hopefully I'll be able to come back later and play through the whole thing more efficiently.
Also I thought the "brain world" was very cool, definitely what I would imagine it would be like to be in someone's psyche.
