Makoto Yaotani cites "Corpse Party" as a direct motivation to make "Shūjin e no Pert-em-Hru", since it exceeded the boundaries of "what commercial games could not do" at the time, especially the depictions of splatter gore. Yaotani also drew inspiration from Indiana Jones, Sherlock Holmes, Father Brown, and the works of Junji Ito for the adventure, mystery-solving, and horror elements of the game.
