App Description

“To set foot on the soil of the asteroids, to lift by hand a rock from the Moon, to observe Mars from a distance of several tens of kilometers, to land on its satellite or even on its surface, what can be more fantastic? From the moment of using rocket devices a new great era will begin...”

— Konstantin E. Tsiolkovsky, 1896


Piloting an asteroid mining ship; you must grab, pull and smash your way through 6 physics based planets fraught with manmade and natural dangers to retrieve a raw source of energy found only at their very core.


Although unarmed, your ship is equipped with a grapnel hook capable of lifting rocks many times the size of itself. Pick up, pull, throw, smash and topple rocks with your grapnel using real world physics to solve puzzles and descend through each level.


Set over 3 stages, each world challenges you to break through the planet’s atmosphere, destroy its defences and descend into its very core to recover a rare but volatile source of energy.
