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.
