Fungi Simulator tasks you with cultivating a mycelial network from a single spore, clicking to expand your fungal presence while offline progression lets the colony grow unattended. As you spread across the world, you'll unlock new mushroom species and watch your empire develop at your own pace. It's an understated idle game for players seeking gentle, low-pressure gameplay with tangible progression.

You should probably pass this one by. It's glitchy as hell. If you leave the game and continue it later, you have negative spores. Also, the achievements are ridiculous! There's one for playing the game for 10,000 hours. That's more than 416 days. That's well over a year! Who will be in-game on a mediocre clicker for over a year!?
This one is technical — no new features, no gameplay changes. But it fixes something that was making every update redownload the whole game. What ChangedPreviously, all of the game's content was packed into a single file. Any change — a texture, a number tweak, a scene adjustment — rewrote that entire file, so Steam had no choice but to re-download nearly the whole game each patch.Now, each mushroom's content is packaged separately. When a future update changes one mushroom, Steam only downloads that mushroom's file. The base game file is now under 5MB. What This Means For YouFuture updates will be much smaller. Content patches should drop from ~280MB to a fraction of that.Faster patch days. No more waiting on a full re-download just to get a small fix.Nothing else changes. Gameplay, saves, achievements — all identical. Important NoteThis update itself is a larger download than usual, because the file layout is changing for the first time. This is a one-time cost. Every update after this one benefits from the new system. What's NextOffline progress is coming in the next update — earn spores while the game is closed, up to 24 hours per session.
