Astatine Glow

Astatine Glow is a neon physics puzzler inspired by the rarest halogen element on Earth.

Pull back the slingshot, release, and send a radiant astatine spark flying. Watch it ricochet off walls and mirror blocks, weaving bright trails across the arena. Every crystal it touches bursts into light: cyan fluorine, green chlorine, amber bromine, violet iodine, and the mysterious magenta astatine itself.

Ignite all the crystals in a level to win. Your spark burns energy as it flies and loses a little more with every bounce, so plan clever angles and chain rebounds to light them all before the glow fades. Fewer sparks spent means more stars and more coins.

Features:
- 12 handcrafted levels with mirror-block layouts that reward smart bank shots
- Simple one-finger slingshot controls with a predictive aim guide
- Glowing neon art style, smooth particle effects, and synthesized sound effects
- A shop with permanent upgrades: extra sparks, a denser energy core, longer aim prediction, and a stabilizing field
- Star ratings, coin rewards, and progress saved automatically
- Fully playable offline, no ads, no accounts

Can you master the angles and keep the rarest glow in nature alive?
