This is a sub-page of Development:Psychonauts.
Note: The subpages here are for covering big/significant subfolders. This main page can document all the stuff that wouldn't warrant such a subpage.
Included in the 2013 build is a collection of development documents from various periods of development including design documents, planning sheets and early playtest guides. They help to paint a clearer picture of Double Fine's ambitious plans, struggles and how the game changed over the course of development.
A large majority of these documents are dated from some period in 2003-2004, mostly coming before some of the game underwent significant retooling which completely changed various levels.
