PC download of the special Kickstarter-only version of the game (full game + extra content). Digital soundtrack collection which includes entire bonus arrangement albums not found in the game. Digital combined manual/artbook/devlog/contributor list/hatemail/occult tome. Your name in the contributor list, along with a 140-character message of your devising.
Disc set of the Kickstarter-only version of the game and the soundtrack collection, fitted inside multiple hand-numbered and color-printed high-quality cases adorned with art. At your explicit request, I will sharpie an upsetting message of my own devising on one of the cases for free. It will be highly unpleasant. Also: everything in the $25 tier.
A classy and understated piece of ominous artwork to hang up in your castle foyer. Printed not on poster paper, nor even cardboard, but on a tough canvas material wrapped around a solid wooden box backing. It's essentially a piece of furniture. The image is larger than your torso, ultra-sinister, and effectively defeats high-energy arms fire at point-blank range--though one of those things is a lie. Numbered and signed. Also: everything in the $70 tier and the $25 tier.
