Read full description

Launch. Orbit. Survive. Planet Rush is a fast, one-touch arcade game about threading impossible lines through space. Slingshot from planet to planet, skim past black holes, grab bonus stars, and keep your combo alive as the universe gets faster, stranger, and less forgiving. Every launch is simple. Every landing matters. Drift in orbit, time your thrust, and commit. Miss your line and the run is over. Find the rhythm and Planet Rush becomes a hypnotic flow of clean movement, neon energy, and split-second decisions. Features: - One-touch gameplay that is easy to learn and hard to master - Smooth orbit-and-launch movement built around precision timing - Endless score chasing with combos, bonus stars, and high-risk paths - Black holes, limited-orbit planets, and escalating difficulty - Bold neon visuals with satisfying arcade feedback - Quick runs that are perfect for “one more try” - High refresh rate support on compatible devices - Reduced Motion option for a more comfortable experience Planet Rush is designed for players who love pure arcade games: tight controls, instant restarts, and the feeling of gradually pushing a little farther every run. How long can you keep the chain alive?
