Grow
Vermehren
Guide your swarm of lights through the night – what you gather keeps glowing in your lantern.
What meets you in the night
Crystal prisms
Your light refracts and multiplies — the swarm grows in flight.
Waiting lights
Lone fireflies join your journey home.
Shadow maws
The dark snaps shut — whoever drifts in is lost.
Will-o'-wisps
Deep in the forest, false lights beckon — follow one and half the swarm is lost.
Vermehren is an arcade run with persistent progress: your stardust, upgrades and best distance remain – every run pays into your lantern.
How it works
- Tap left/right or use the arrow keys to switch lanes.
- Crystal prisms multiply your lights, waiting lights join you – shadow maws swallow some. With no lights left, the run ends.
- The farther you get, the more stardust you gather. While you are away a small gift keeps glowing – honestly capped.
Your lantern forgets nothing
Every run pays in: what you gather keeps glowing — on your next visit the swarm waits right where you left it.
- Stardust and upgrades are yours for good.
- Your best distance counts — including against your friends.
- While you're away a small gift keeps glowing — honestly capped, no pressure.
