About This Game

In biorhythm, you play as bacteria lost in the human body. As the heart beats, everything in the body moves to the rhythm. You'll swim through the bloodstream to the beat, exploring, fighting other microbes, and duplicating yourself as you go.

As the progression of your lifecycle weakens the body, you'll face terrifying challenges; vicious microbes, hungering white blood cells, intense fever.

The game runs 2.5 - 3 hours. It features hand-painted art, an orchestral score, and a thrilling story.

  • Grow a swarm of bacteria and explore the human body at a microscopic scale
  • Encounter strange microbes & fearsome white blood cells
  • Live as an outsider in a vast, incomprehensible system

Created by Brady Soglin. Art by Anna Cich & Jackie Lombard. Sounds by Dylan Payne & Bobby Volpendesta.
