Zen Astronaut is a space flyer — navigate your astronaut through asteroid fields and debris clouds in zero gravity. Hold your jetpack to rise, release to fall. How far into deep space can you venture?
💡 Tips & Strategy▾
Jetpack is more responsive than a helicopter. Brief taps give precise altitude control. The astronaut responds fast.
Watch the oxygen meter. Collecting star fragments refills oxygen. If oxygen runs out the game ends — prioritise fragments over pure distance.
Asteroid fields cluster. After 150m asteroids begin grouping in pairs and triples. Anticipate the second asteroid immediately after clearing the first.
