Several of the upper Indiegogo tiers include(d) additional items with additional character info and lore outside of that which we're able to glean just from playing the game, and concept art. Namely:
- The digital Fran Bow diary
- Fran Bow: the Documentary
- Potion from the collector's edition
I think Killmonday on the blog/vlogs said something to the effect that they might start selling shirts, posters, and other merchandise, though probably not the exclusive stuff mentioned above. So it would be nice to find contributors with access to this information.
Also, if this campaign page is to be trusted, there is one (1) outside person who has played the Mr. Midnight minigame. I hope we find this person!
