Blast Off - Game Description:

Blast Off into a universe of gravity slingshots, lost astronauts and bizarre planet systems.

Use your rocket ship to rescue astronauts and carry them through the warpgate to safety. But be careful! The ever-present force of gravity can be your best friend AND deadliest foe.

The emphasis of Halfbrick Blast Off is predicting the effects of gravity and using very minor corrections as you go.
