How do I access the missions?

To access the missions, select the ‘Missions’ icon, which looks like a flying saucer, on the left when on your home planet.

Please note that planets and meteors unlock in a certain order, so you need to successfully complete each planet before moving on to the next planet (you do not need to complete the meteors before moving on to the next planet though if you do not wish to).

New galaxies require you to be a certain level before attempting them, so if you complete all the missions in your current galaxy prior to reaching the level requirement for the next level, you will need to repeat some missions (you may wish to try and achieve some medals while doing this) to level up to the required stage before attempting the next galaxy.
