One tap, endless swarm.
Autofire clears the swarm around your spark core. When the embers close in, one tap blinks you to safety. Level up mid-run with a 3-choice draft, collect weapon shards, and push through 5 biomes and 60 stages — or dive into the endless Swarm for a pure survival run.
Pick a primary weapon, a secondary weapon, and a passive. Mid-run drafts add temporary boosts on top of this; the loadout itself only changes between stages.
Choose one:
Weapon shards drop from kills and elites — collect enough of a weapon's shard to raise its rarity tier (Common to Legendary). Companions are cosmetic + a small passive, unlocked by clearing each biome's boss stage.
