I hardly write reviews, it's not my thing but I am really frustrated with this game... I thought it would be so fun but, oh, how mistaken I was... It's so annoying and frustrating. You will be walking on a surface of a celestial body in first person, where you can't look up nor down, just forward and to the sides, also you can't see very far too. It's pretty much like the Spore's worlds, but worse because it is empty and in a very smaller scale. There's no tutorial nor explanation of what you have to do. That means you will first be worried if your mouse is working correctly, since you can't look up and down, then you may think that it may be an issue with your gamepad, if it is plugged in. But then you will understand that this is just an annoying limitation for some reason.
Without knowing where to go or what to do, you will, eventually, discover that the celestial body up there is actually a map and by "upgrading" your, err, "gravitational gun" you can drag it around, which will also be a pain since you can't look up you will have to align yourself with it.
There's a map and a kind of travel machine that is really, really weird and a pain to use it properly. You will find yourself flipping switches without knowing what you may be doing, as always...
In sum, you will be aimless walking on a empty surface doing stuff that you are not sure what nor why.
I would not recommend this game to anyone, not even for its art.
