I've about about 3-4 hours into it so far but there's something that's not quite clicking for me and the game. It might be that I had my fill of passively digging in Terraria after about 10 hours or the fact that they play and look similar (and that fact that my memory of Terraria mechanics haven't entirely faded made the contrast even less bearable).
The procedurally generated "aliens" might not be my style either. They look less like aliens and more like chimerical farm animals mixed in with some predatory ones with random attached pokemon appendages. I know it's an open beta too but I really hope they sort out the "alien" neighing, bah-ing, quacking and things like that.
Fighting them isn't very interesting as of right now either, there's no control except for aiming left or right when it comes to melee weapons and Terraria at least let you have some control over where you stabbed your spear or swung your chain weapons which added a bit of depth. Another nitpick too is my character appears to be left handed but he switches to his right hand when swinging in one direction.
I understand a lot of these are minor issues, it's a beta, and generally come down to preference sometimes but when they have a "real/hard" release the devs should sort out things like being able to pick up one item out of a stack, more information than "be prepared for anything" (even though as far as I know it's the same event), information on pixels, what the "sun" bar is and other minor mechanic annoyances. Right now they have a bit of polishing to do, which I understand as it's labeled an open beta.
Schematics huh. Sofar ive dug pretty much to hell and walked an entire circle over the entire planet and only got 2 schematics. Which were for a god damn mushroom hat and a mushroom door. Definately not invading the universe with those. Sweet lord why............ The only futuristic thing you brought with you from your destroyed homeplanet is a "matter manipulator" and that thing gets schooled by caveman stone tools. My human wasnt probably very smart from where he came from. 
He also forgot, or his computer forgot to tell him that coal ore and unrefined wood can be used as fuel *nudge nudge*. I guess we don't get past that in the future as a standard, although I'm assuming there's a starbound flux capacitor floating around there somewhere out there.
