About

Orbitap

Read full description

Orbitap is a one-tap arcade game where you launch a planet between orbiting stars in an endless gravity-hopping chain. Time your taps to release from orbit, fly through space, and get captured by the next star's gravity well. Miss a star and you're lost in the void. HOW TO PLAY • Your planet orbits around a glowing star • Tap to release — the planet flings off tangentially • Aim for the next star's gravity well to get captured • Chain captures to climb higher and score more FEATURES ▸ Gravity Physics Real orbital mechanics drive the gameplay. Every release angle matters — master the timing to chain perfect captures. ▸ Escalating Challenge Orbit speed increases with each capture. Capture radii shrink. The difficulty ramps naturally until you misjudge a release. ▸ Combo System Capture stars in quick succession to build combos with escalating visual and audio feedback. ▸ 8 Biome Environments Journey through unique biome environments, each with its own color palette and atmosphere. ▸ Stardust & Cosmetics Collect stardust to unlock 10 unique planet skins and visual effects. ▸ 3 Lives with Revive Get 3 chances per run. Watch an ad to continue from your last captured star. ▸ Daily Challenges Compete on seeded daily puzzles where every player gets the same star field. ▸ Satisfying VFX Particle bursts, screen shakes, shockwave rings, and colored flashes on every capture. How far can you orbit?
