It’s taken me a really long time to get far enough to see some of the features in this game. But I just got a new high score and holy crap, there’s so much more to this game than I thought. So many different kinds of planets and cool features. I wonder what else I haven’t discovered yet.
Fun graphics, easy to play! The music is my favorite part.
