The documentary "Making Frog Fractions" is now available on the Frog Fractions download page, for backers at the $40 level and up. It is under the "eBooks" platform.
If you don't know about your download page, you can retrieve it here. If that doesn't work for you, or you can't find it, send me a Kickstarter message! Also look on the "eBooks" tab first because that's where the documentary is.
The documentary pack consists of a commentated playthrough, an art book, the FF1 source code, and a set of historical builds of FF1 showing the progress of development over time.
Please don't distribute any of these items, but do distribute (for free) things you made using them, such as let's-play videos of the historical builds, or Frog Fractions Ultimate Edition to which you added a bunch of additional secrets.
