Gravloop One orbit. Two rings. Zero mercy. Gravloop is a precision arcade game where you pilot a ship locked in perpetual orbit between an inner and outer ring. Tap to thrust outward. Release to fall back in. Catch gems. Dodge everything else. Simple to learn — genuinely hard to master. The longer you survive, the faster your orbit spins. What starts as a calm loop becomes a white-knuckle blur. HOW IT WORKS. Hold anywhere on screen to push your ship to the outer ring. Release and gravity pulls you back. Fly through gems to build your combo multiplier — chain enough together and you hit FEVER mode, where every gem is worth far more. Keep the chain alive. Don't get hit. 6 DISTINCT MODES • Classic Beat — The foundation. Surge events expand the rings and flood the zone with gems. • Hyper Orbit — Assault waves. Homing comets. Relentless from the start. • 60S Rush — One minute. Maximum score. Every hit costs you points. • Cosmic Abyss — Tiny inner ring, vast gap. Surgical precision required. • Zen Horizon — Gems only, no hazards. Pure flow state. • Celestial Siege — Destroy celestial bodies. Each one you clear grants a special power.

You can trim the middle sections down if Apple's character limit is an issue — the first and last paragraphs are the most important to keep intact.
