Your tower. One tower. An infinite tower.
Build a god-forged rampart in this chill incremental tower defense idler and watch it evolve from humble sentinel to unstoppable cosmic siege engine. Idle through endless enemy waves while your power compounds — then tinker with 2744 runewords crafted from 14 runes across 4 slots to squeeze every drop of potential from your growing arsenal.
The deeper you go, the stranger the combos get:
Bounce + Splash = chain-death ripples shredding entire packs at once.
Combo + Laser = ramping damage spikes melting the toughest targets.
Sniper + Kaboom = one-shot a foe and detonate the horde.
Prestige to unlock new layers of upgrades. Each loop multiplies your might, opening rune combinations you couldn't reach before. Crush epic bosses, repel daring adventurer raids, and conquer escalating challenges — all feeding back into your ever-growing incremental engine.
Numbers go up. Forever.
