About Mushroom 11
Mushroom 11 is a game in which you shape an amorphous organism by removing its cells; new cells immediately grow in their place. You guide it through a mysterious world, navigate brain-teasing obstacles and face swarms of mutated creatures as you uncover the nature of the devastation from which it emerged.
The game features eerie visuals and an ethereal soundtrack by The Future Sound of London.
