We have currently three different game modes included.
Practice:
Chose one planet and look for powerups, diffucult spots and the bomb.
You can do everything you want in this mode except getting in the highscore
list ;)
Time Attack:
Try to fly through the planet as fast as possible. You can turn on/off
the ghost ship in the options menu.
Single Player:
Chose a trip and try to complete all planets one after another. Try
to earn extra points by destroying guns or collecting powerups. If you
get the bomb to the surface you will automatically go on to the next
planet.
