Use the motion of your phone to control your ship - twist it sideways to turn your ship and aim. The ship is always pointed up.

In space there is no up or down.

And nobody can hear you scream.

Except they can, if they happen to be listening on your comms channel. But even so, before your cry has inched its way to them at the slow, slow pace of lightspeed you'll be long dead, a dessicated corpse floating in the infinite void.
