It could have been good if all the planets were actually playable.
It felt like half a game, and another six months to bake would have probably turned it into a great game with some replayability. Put a gun to my head, and I couldn't tell you the plot, but I remember both "some" fun, and a lot of frustration of how short it was.
I really wanted to like it, but just couldn’t get into it. It was completely forgettable for me, and I like nearly every game that has a sci-fi setting. My bar is very low for that genre, but this one was not engaging at all for me.
