Solr let’s you create planets and stars in a sandbox environment.
Start fresh in playground mode, or load from a saved system.
Planet creation:
tap to create a planet or star
OR
tap and hold, letting go when the gray sphere reaches the size you want
swipe to make that thing move!
Put the switch in its “on” position to make stars.
