About
HyphoSphere is a fungal idle game where you build a mycelial empire from a single filament to a cosmic singularity. Click to harvest nutrients, construct living organisms, and watch your network spread across the planet ... and beyond.
Start with a single Simple Hypha and unlock 10 distinct organisms, each with its own identity on the living canvas:
Rhizomorphs : robust cords that explore new substrates
Mycorrhizae : symbiosis with tree roots, feeding both you and the forest
Carpophores : the visible mushroom, a spore factory in full bloom
Forest Network : you control the Wood Wide Web
Cordyceps Parasites : infect insects, make them work for you
Fungal Consciousness : the network thinks, optimises, expands
Mycelial Singularity : you have transcended biology. The cosmos is your substrate
The central canvas is alive. Your mycelium pulses, filaments grow outward, particles drift and burst. Random events appear at any time :
Bioluminescent Spore : catch it for ×7 production or 15 minutes of nutrients in an instant
Spore Storm : gather drifting spores across the canvas
Bacterial Invasion : repel the attack before your network is damaged
Cosmic Mycorrhiza : rare, radiant, extraordinary
When your empire grows large enough, trigger Sporulation: reset everything and earn Primordial Spores. Each spore grants a permanent +5% production bonus. The cycle begins again : faster, richer, deeper.
From your first harvested nutrient to billions of clicks and cosmic transcendence : 100 achievements track your journey and power up Symbiotic Vitality, a bonus that scales with every milestone you reach.
HyphoSphere is designed to be streamed. Connect your Twitch channel and let your viewers become part of the network:
!click : viewers click the mushroom for you
!boost : vote for ×3 NPS for 20 seconds
!invade : vote to trigger a bacterial invasion
!buy : community votes to purchase an organism

Reviews
Honestly, it's hard to recommend this one. I just did my first prestige and called it quits. There's quite honestly nothing going on. It's a numbers go up incremental game, which is fine, but there's nothing that makes it worth it. Imagine cookie clicker where the only upgrades were "X gives double", and prestige only gives a stacking 5% buff. And weirdly, the game is pretty punishing to idle, since half the random procs are detrimental if you fail to click them? So it's an anti-idle game with no decision making. I kept waiting for something else to happen, but if I haven't experienced it by the first prestige, and that prestige gave a single 5% buff, I don't think it's going to happen. It's an accomplishment to release a game, but it's hard to recommend anyone spend any money on this when it's a glorified screen saver.
Idle & Incremental Lovers doesn't recommend HyphoSphere: [i] Beautiful minimalist artwork, sadly the rest is pretty bad. Basic QoL features are missing and the prestige system is awful: you just get 5% more production (additive, not multiplicative, facepalm).[/i] + I had high hopes due to the original fungal theme and beautiful artwork. - Prestige system is way too linear, no power creep at all. - As a consequence, numbers grow up... if you have a magnifying glass. - Everything is written in very small characters, you have to stick to your screen to be able to read. - Music is pretty repetitive and the balance with SFX is awful: clicks make a nasty noise way louder than the music, and there's no separate music/SFX sliders to fix this. I had to mute. - No fullscreen. - Contextual information pops up as Windows' windows, not immersive at all. *What kind of vehicle does a mushroom drive? A spores car.* Found this review helpful?

Ce jeux est un mauvais IDLE : prestiges inutiles, très peu d'ameliorations Et faut pas avoir de problèmes de vue comme moi : tout est écrit tellement petit ... Par contre ... Je trouve ca juste BEAU C'est mon nouveau fond d'écran animé
