This is the most stellar (lulz) and relaxing game I’ve played in a while.
“It combines classic space shooter gameplay with mathematically generated scenery and today’s special effects. You fly around, collect some things, shoot up some other things, avoid getting shot, all while watching the scenery and models. Alternatively, you can switch to viewer/editor mode and make some cool images with it or fiddle with parameters to the scenery generator - it can double as artistic tool.”
