About Lone Fungus
Lone Fungus is a Metroidvania set in an ancient world built by mushrooms, where you play as the last mushroom alive. You explore a huge interconnected world, uncover secrets, gain abilities and fight enemies. The game has ten distinct areas, each with its own enemies and obstacles.
Explore the world
Searching every corner of an area can reveal secrets and rewards, including Relics, Emblems, and upgrades to your Health or Mindpoints. Progression through the interconnected world is gated by abilities you acquire as you play.
Combat and builds
Combat combines sword attacks, spells and parrying. You can parry anything that would normally damage you; parrying projectiles sends them back at foes. Parrying is optional, and Emblems found throughout the world can change how it works. For example, an Emblem can make a parried projectile home in on enemies but deal less damage, cause your cap to damage nearby foes instead of bouncing a projectile, or destroy multiple projectiles around you with the Vortex Emblem.
Relics offer another way to customize your character. The game contains 60 Relics: some alter healing, increase sword damage or add protection, while others support builds focused on defense, healing, speed, melee attacks or spell-casting. Defeating bosses grants permanent upgrades, including spells, new moves and types of attack.
Bosses and platforming
You can challenge 33 bosses to acquire new abilities. Each boss has distinct attack patterns, clear cues before striking and limited randomness, so you can learn their techniques and aim to win without taking damage.
Platforming challenges are optional side-room content, so you can progress through the adventure without taking on its hardest precision platforming. Practice rooms let you refine your skills and tackle more demanding challenges. The game also includes acrobatic movement and fast, responsive combat.
Difficulty and assist options
You can choose from four difficulty modes and customize controls, including a dedicated down-attack button. Assist Mode offers six options that can be enabled to make the game more accessible or to change how you play:
- Platforming Pause: lengthens the pauses between platforming mechanics such as Mushmovers.
- Magic Platforms: adds platforms to some sections to make them easier.
- Worldmap Hints: shows missed items in rooms you have already visited.
- Stronger Sword: increases your sword's base damage.
- Infinite MP: removes Mindpoint management, letting you heal and cast spells without limit.
- Invincibility: prevents you from dying.
