What You'll Learn

Mushroom 11's seven chapters
Mushroom 11 is a 2015 puzzle-platform game developed and published by Untame. The game has received positive reviews for its unique mechanics and theme. Each of the seven chapters has fifty collectibles scattered throughout.
In the first chapter, the player is introduced to the game mechanics. The player begins in a hole in the ground and makes their way through a desolate city, both over and underground. The scenery consists of destroyed buildings and tunnels, with a few bits of lava here and there. The player needs to collect blue fluorescent mushrooms and activate checkpoints, which become more important as the chapters progress.
In the second chapter, the player encounters fire worms and a big worm that resembles a garland. The player must absorb the isthmus that keeps the worm hanging, causing it to fall into a lava pool and freeing the tunnel above. The player then needs to use the steam flow to get into the tunnel and move upwards to finish the chapter.
In the third chapter, the player continues to navigate through tunnels and encounters a giant spider. To defeat the spider, the player must swallow its eyeballs by moving upwards and downwards on its legs.
In the fourth chapter, the player encounters a catapult puzzle and must use their skills to get past it.
In the latter chapters, the player continues to navigate through the post-nuclear world, solving puzzles and collecting items. The final boss introduces a brilliant new mechanic, providing a satisfying conclusion to the game.

Post-nuclear world setting
Mushroom 11 is a puzzle-platform game developed and published by Untame in 2015. In the game, players control a green mushroom by deleting parts of cells while it simultaneously regrows. The mushroom can be split and shaped to solve puzzles. While the number of chapters in the game is not explicitly stated, there are at least seven chapters, with references to a possible eighth chapter, which could be an epilogue.
The game is set in a post-apocalyptic world where civilisation has fallen, and all that remains is rubble, mayhem, and low life forms that can survive the harsh terrain. The player controls a mushroom or fungus, exploring an empty Earth. The game's creative lead, Julia Keren-Detar, has stated that the mushroom could refer either to a fungus or to the cataclysmic cloud of an atomic bomb.
In the game, players navigate the landscape, solve puzzles, take on bosses, and soak up small insects and other mushrooms for points. The mushroom can be shaped and split by deleting parts of its cells, allowing players to create new branches and direct its growth. This unique mechanic received positive early critical responses and was nominated for the "Most Innovative" game of 2015 by IGN.
The post-nuclear world setting of Mushroom 11 is one where most life on Earth has ended, and magic has resurfaced due to the properties of the mutagenic bomb. The bomb was dropped on what was once North America, and its aftermath included abandoned military vehicles, aircraft, and blockades, hinting at mobilisation, martial law, or active fighting during the war. The Candy Kingdom, one of the new civilisations that arose after the war, is built atop a pond of nuclear waste, and its inhabitants have recovered or developed new technologies, such as universal translator devices and holographic newspapers. However, most human inventions, especially those related to transportation, remain lost to them.

Unique mechanics and theme
Mushroom 11 is a unique puzzle-platform game that stands out for its innovative mechanics and post-apocalyptic theme. In the game, players control an indestructible green mushroom in a post-nuclear world devoid of humans. The mushroom's ability to regenerate and transform into an infinite number of forms is central to the gameplay. Players must strategically delete and regrow parts of the mushroom's cellular structure to navigate through the game's levels and solve puzzles.
The game's mechanics are designed to be challenging yet intuitive. Players use their mouse buttons to manipulate the mushroom's form, erasing parts of its structure with the right mouse button and regrowing them with the left. This unique control scheme allows for a high degree of precision and strategy in how players approach each puzzle. The game also features a generous checkpoint system, allowing players to take breaks between puzzles and return to them later without losing progress.
The game world of Mushroom 11 is meticulously crafted to complement its puzzle mechanics. Set in a desolate city with destroyed buildings and tunnels, the environment presents players with a variety of obstacles and challenges. Players must guide their mushroom through hazardous terrain, including pools of lava and purple acid, using their regenerative abilities to adapt to the environment and overcome obstacles.
The game's post-apocalyptic setting and absence of human characters further contribute to its unique atmosphere. As players progress through the chapters, they encounter remnants of a world left behind, including fire worms, giant spiders, and boss battles against mechanical creatures. The combination of challenging puzzles, innovative mechanics, and a captivating world has earned Mushroom 11 critical acclaim and nominations for its innovative design.
