Your astronaut is stranded on a dangerous alien planet with a rocket pack on his back. Tap anywhere to fire a short boost. Tap again and again to climb higher. There is no holding: every tap is one burst.
Every boost burns fuel. Grab the yellow fuel cans to top up. If the tank runs dry you can't boost and you start to fall. Hitting the ground with no fuel ends the run.
You start with 3 shields. Hitting a rock, a meteor, a spore cloud or the ground costs one shield, and the third hit ends the run. Blue shield pickups restore one (up to 3).
Every 30 seconds you reach a new stage: the planet changes colour, everything gets faster and closer together, and new hazards join in: gap pillars, falling meteors (watch for the red warning at the top), spore clouds and moving gaps. Every run is laid out differently.
Scoring: points for distance, for every obstacle you dodge, for fuel cans and shields, and a bonus for each new stage. Each stage raises the score multiplier (up to ×5).
On a computer, click or press Space or ↑ to boost. P pauses, M mutes.
