I'm having a little trouble because I am in the first stage and then I get too far away. There's no more matter. I try to go back, but there's no matter anywhere... I've only absorbed one :')
EDIT: Okay I'm having a lot of trouble. I keep running into dead ends. Also, I need to gather 5K when I'm only in the first stage, is that intended? It gets hard when everyone's a star and you're not :')
