I originally got this on Steam. I hate Steam. Happy it released here! It's a lot like Terraria but the worlds are smaller and they wrap. But you have more worlds to play on. You have to play the main story quest (it seems). But it's a Sandbox so you can do it at your leisure. Terraria allows for you to play whichever character on whichever world at any time. This...not so much. However, I'm starting to wonder if you have one galaxy which all your characters share and you could run into worlds of you other characters? In the beginning, the movement wasn't great and it seemed to eat up a lot of resources. It's much improved since then. There is this bug with the layers though. Over time you start seeing the layers turn black. Apparently they know about it but haven't fixed it. And then there's Moddng. Starbound supports and encourages modding. There are a lot of mods out there which can make your game unique. Make sure they're made for your version though.
