    How to unlock Galaxy Explorer

    Self-explanatory, merely unlock any 20 levels, adventure or challenge (blue or red). The beginning levels are pretty easy and are only around 30-60 seconds long each. It shouldn't take you long to do this if you get a couple medals in each of the introductory levels, as the game doesn't get hard until you get past adventure level 20.
