Collect loot!!  You’ll use it to upgrade your ship.  Once you’ve collected enough loot the Space Dock will unlock.  Let the upgrading begin!  Upgrades will help you get farther and beat your friends scores easier.  You’ll find more valuable loot the deeper into each Galaxy you travel.  Loot also gets more valuable the higher the Galaxy you’re in. In some Galaxies you’ll even find new types of loot!  Once you’ve collected enough loot enter the Space Dock to buy an upgrade.  Different choices will help you in different ways.  Choose what works best for you!
