Shuujin he no Pert-em-Hru is a Japanese freeware role-playing game developed in RPG Maker Dante 98 II by Makoto Yaotani. The phrase “Pert-em-Hru” references the Egyptian Book of the Dead, so the title can be understood as meaning “The Book of the Dead for the Prisoners.” The game was made by a two-person team, although Yaotani carried out most of the development work, and it took about a year and a half to complete.
