Take time to figure out which controls work best for you. Some prefer playing with mouse and keyboard while others use only keyboard. You can disable the mouse controls in the ingame menu is you don’t want to use them.

IMPORTANT: If the game runs slowly, decrease the quality in the ingame menu.
If you have a fast computer turn on the ‘Trails’ in the ingame menu to get awesome graphics.

If you think the game is too easy try the hard mode.

If you like all of the space game missions in spacecraft, share them with your friends!
