Mycorrhiza is an immersive visual novel that draws inspiration from horror manga, particularly the works of Junji Ito and Masaaki Nakayama. Set in a surreal landscape, players follow the protagonist, Scott, as he navigates a nightmarish reality where morality is twisted and strange phenomena occur. The game features three distinct story arcs, each exploring unique horrors, including a bizarre plant that alters animals, a disturbing comedic trend, and an enigmatic building that ensnares its occupants.

The game is presented in a captivating manga aesthetic, enhanced by animated character art created by a professional manga artist. It also emphasizes a rich audio experience, making the narrative even more engaging. To ensure accessibility, Mycorrhiza includes visual audio cues and offers a dyslexic font option, making it a thoughtful choice for a diverse audience.
