Phosphorus Glow

Phosphorus Glow is a moody glow-in-the-dark maze adventure. You are the last firefly, drifting through winding labyrinths where your own light is the only thing keeping the darkness back.

Touch and hold to glide through the maze. Your light drains every second, so collect glowing motes to recharge before the dark closes in. Shadow wisps patrol the corridors and burn away your glow on contact. Reach the swirling cyan portal to clear each level, and gather most of the motes along the way to earn three stars.

Features:
- 12 handcrafted-difficulty mazes that grow larger, darker and more dangerous
- Smooth touch controls with wall-sliding movement
- A living darkness effect: your light radius shrinks as energy runs low
- Shadow wisp enemies, glow motes, magnet and shield power upgrades
- A coin shop with permanent upgrades: bigger glow, energy cells, shields, magnets
- Star ratings, persistent progress, sound and vibration settings

Can you keep the last light alive?
