Our take on Jimmy and the Pulsating Mass

The game's unusual mix of childhood viewpoint, jokes, and disturbing subject matter sacrifices tonal consistency. Players who prefer a steadily serious narrative may find the shifts between humor and subconscious horror less cohesive than a conventional RPG presentation.

What is Jimmy and the Pulsating Mass?

Jimmy and the Pulsating Mass is a Japanese-style RPG set inside the dream of an eight-year-old boy.

After an alien entity threatens Jimmy's family and the dream world, he travels through its landscapes to confront the Pulsating Mass. The game uses turn-based combat and places strong emphasis on exploration. Jimmy can take the forms of monsters he encounters, using these transformations to affect the world in different ways. Each form can gain levels, increasing its statistics and adding abilities. The story addresses adult themes through a child's viewpoint and combines jokes with disturbing imagery. The game draws influence from SNES-era Japanese RPGs and Yume Nikki.
