Grow a spire.
Hold the Blight.
An idle tower defense in a pitch-black fungal hollow. Your spire aims and fires glowing spores by itself. Your only job is to decide what it grows into.
The loop
The same compulsive loop as the idle defense classics, set in a moody, glowing 3D diorama built for one-handed portrait play. You never aim. Every input is a tap on a big button.
Kills drop Nectar. Spend it mid-run across THORN, and ROOT. Every purchase changes the spire you can see.
The Blight crawls in from the dark, visible only in your spire's glow. Your spire aims and fires by itself. Waves escalate and a boss arrives every ten.
Every run ends by design. When the spire wilts, your Spores go into the Mycelium Workshop for permanent levels, so the next run starts stronger.
Close the app and your mycelium keeps harvesting Spores for up to 8 hours (longer with research). Come back, collect, and push one wave further than last time.

Grow your Spire
You are the Sporewright, keeper of the last living Mycelial Spire. It is the only light in the world, and it grows with every upgrade you buy, through five stages.
A single glowing teal mushroom on a root stump. Every run starts here.
A twisted trunk with shelf fungi and a cap of glowing spore bulbs.
A tangle of deep-blue roots bristling with glowing mushroom caps.
A tall dark trunk spreading a wide canopy of violet shelf caps.
A luminous trunk ringed by tiers of violet caps on a wide root base. The long-term goal.
THORN buys add launcher bulbs to the cap, glowing pinker as Critical Chance rises.
BARK buys armor the trunk in shelf-fungus plates and raise a shield dome.
ROOT buys spread glowing root veins across the forest floor.Three upgrade trees
22 in-run upgrades bought with Nectar, plus 2 that live only in the Workshop. Costs reset every run, so every run starts with cheap buys, and each upgrade has a permanent Workshop twin you level with Spores. You start with 10 and unlock 14 more as your best wave climbs.

Bestiary
Fifteen kinds of Blight, three of them bosses. Each creature is visible only once it enters your spire's glow, and each one asks a different question of your build.
A hulking boss that walks in on every tenth wave, announced by a red pulse and a camera push-in. Its footsteps shake the screen, knockback can't move it, and Glowcap Orbs can only wound it, never destroy it outright.
The Blight Heart's own boss. Every 7 seconds she calls two Cavern Burrowers up beside her, and they slip under your spire's fire. From wave 15 on Tier 5 and deeper, she takes turns with the Rot Colossus.
The endless swarm. Crawls to the spire and chews on it, once a second.
Twice as fast as a beetle and frailer. It reaches the spire before you notice.
Slow, heavy and hard to push back. The screen shakes when it slams into the spire.
Stops just outside your starting range and lobs rot globs that always hit.
Answer: buy Range.
Never attacks. Halves the damage taken by Blight around it, marked by a violet ground ring.
Bursts into three Mold Crawlers when it dies.
Tunnels in where spores and orbs can't reach, then surfaces right beside the spire.
Answer: close damage, Barbed Cap, Health.
A regrowing shield soaks damage first. Chip damage loses to it; burst damage wins.
Hovers and flickers into a ghost, out of reach. Spores already in flight lose it.
Answer: Attack Speed and Multishot.
Any Blight can spawn as a violet-rimmed Elite: four times the health, harder hits, triple the rewards. They show up deep into long runs, and from the first wave of Tier 5.
When the hollow is packed, new arrivals merge into one of their kind, which swells up and pulses. Same total threat, same total rewards.
The third boss waits below The Dead Canopy. On Tiers 7 and 8 it claims every fourth boss wave from wave 20, hides behind a shield that grows back, and every 9 seconds calls three Glimmer Moths down on your spire. Knockback can't move it.
Drifts in as a ghost your spores pass through, then turns solid to spit from range.
Tunnels up close under a crystal shell that grows back. Glowcap Orbs only wound it.
A slow, shielded maw that spits out two Mold Crawlers every 6 seconds and barely budges when pushed.
Eight tiers
Reach a wave milestone to unlock the next tier: tougher Blight, bigger payouts, and a new look for the hollow. Each tier also pays Spore rewards at seven wave milestones. The two deepest tiers open only to a spire that has Rebloomed.

The long game
Past the Workshop, six long-term systems open one by one as you play: research that runs while you sleep, cards to collect, rites to call down, missions and a 100-rank ladder, a prestige talent tree, and spire skins. It takes more than 150 hours of play to reach the seventh tier, and our pacing simulator had not reached the eighth after 238.
Hours of play with the app open, measured with the game's pacing simulator for a player who checks in four times a day (about 4 hours of play), on two random seeds. Idle time only feeds offline harvest and research timers. Tier 8 was not reached within the 238 hours we simulated. Your pace will differ.
Timed research on a real clock. Pick a line, pay in Spores, and it finishes while you play or while the app is closed. You start with one culture vat and can grow to five. Effects apply from your next run.

Luminite, the cyan crystal, drops from bosses and elites and comes with first-time milestones, missions, achievements and rank-ups. Spend it on pods: a Spore Pod holds 3 cards for 60 Luminite, a Grand Pod 10 for 180, the last one rare or better. Duplicates level a card from 1 to 5, and bad-luck protection guarantees an epic within 16 cards and a legendary within 150.

Ultimate abilities you call down mid-run. Equip up to three; each charges on its own cooldown beside the arena, and one tap unleashes it. Level Power, Duration and Cooldown for good, and from Rank 20 auto-cast can fire them for you at the right moment.
A ring of spores bursts out, hits every enemy once and hurls it back.
Living lightning leaps to the nearest enemies in Range, again and again.
A golden mushroom sprouts; every kill pays more Nectar and Spores.
A circle of caps rises; enemies inside crawl and wither.
A violet fog eats a share of every enemy's life each second.
Every volley also looses homing spores at the toughest enemies.
Three daily missions, and from Rank 4 three weekly ones, each set with a chest for clearing it. Sixteen achievement families track everything from bosses broken to cards maxed. Nearly everything you do earns XP toward Sporewright Rank, and each new rank pays Luminite and Spores, opens slots and systems, and every fifth rank adds a free pod.

When a cycle slows down, let the spire Rebloom. The Workshop, ladder unlocks, Spores and tiers reset, and you gain Mycorrhiza for a permanent talent tree. Research, cards, rites, rank, skins and Luminite all stay, and every Rebloom adds +5% Spores for good. Talents can start runs at a later wave, auto-buy upgrades, or keep tiers and unlocks through the next Rebloom.

Idle, your way
While you slept…After five minutes away, your mycelium harvests Spores for up to 8 hours, based on your recent runs. Level Offline Harvest in the Workshop to boost it, and research Deep Dormancy to stretch the cap to 16 hours.
1x and 2x from the start. 3x unlocks when you first reach Tier 3 and 4x at Tier 4, and Time Dilation research adds 5x and 6x.
Runs are saved at the end of every wave and pause when you leave the app, so you can resume a run even after the app is closed.
Waves 10, 25, 50, 75, 100, 150 and 200 each pay a one-time Spore reward, in every tier, and Luminite the first time you reach them.
An idle tower defense for phones. You keep a single Mycelial Spire in the middle of a dark fungal hollow. It aims and fires on its own while waves of Blight close in. You spend Nectar on upgrades during the run, and Spores on permanent Workshop levels between runs.
Yes. There are no banner or pop-up ads. Rewarded ads are optional: a button tells you the reward before you watch, with a small daily limit. The one-time Ad-free Pass in-app purchase gives you the same rewards without the videos. Nothing else is sold: Luminite, cards and pods are earned only by playing.
No. The spire picks its own targets. Every input is a tap on a big button, laid out for one-handed portrait play.
Every run ends by design: the Blight grows faster than any spire can. When yours wilts you collect Spores (plus an end-of-run bonus), spend them in the Mycelium Workshop, and start the next run stronger. Hitting wave milestones unlocks deeper tiers.
Yes. After at least five minutes away, your mycelium harvests Spores for up to 8 hours, and a popup lets you collect them when you return. A run in progress pauses and saves, so you can resume it.
A long time. Beyond the Workshop there are six long-term systems: Sporeries research, Mycelial Cards, Mycelial Rites, missions and Sporewright Rank, Rebloom and spire skins. On our pacing simulator, a player who checks in four times a day (about 4 hours of play) first Reblooms after 10-13 hours, opens Tier 6 at 65-67 hours and Tier 7 at 160-167 hours, and had not reached Tier 8 after 238 hours. Maxing every research line takes 8 weeks or more.
Sporewright's prestige. Once you reach wave 65 on Tier 4, you can let your spire Rebloom: the Workshop, ladder unlocks, Spores and tiers reset, and you gain Mycorrhiza to spend in a 24-talent tree. Research, cards, rites, rank, skins and Luminite stay, and every Rebloom adds +5% Spores for good. Tiers 7 and 8 open only after Reblooming.
A cyan crystal you earn by playing: from bosses and elites, the first time you reach each wave milestone, and from missions, achievements and rank-ups. It buys Spore Pods for Mycelial Cards, unlocks rites, their cooldown upgrades and auto-cast, and can finish research early.
