Disclosure: I backed the Dies irae ~amantes amentes~ Kickstarter project.
Light have showcased a preview of the design for the physical PC release of Dies irae ~amantes amentes~ in their latest Kickstarter update. This physical release is a Kickstarter/BackerKit reward that will only be available to backers and BackerKit till 11th June at 11:59PM UTC time so if you are interested in a physical copy it may be worth grabbing it now. It will come in a tall DVD-rom case with an outer cover slipcase. Light released the following images below, with the design still subject to change.
Dies irae ~Amantes amentes~ is now available for PC via Steam. A PS Vita digital release is also planned.
