I like the direction it's going. I really do. The only real issue I can see so far is its early stage of development. When you are constantly living in fear of the "Falling" glitch, that's something to be said for a game that tries to be so immersive that it plays you the song of your respirator's people. If you don't know what I'm talking about, I'll explain... You have to constantly listen to your own breathing.
Oh, you meant the game-breaking and ever-lurking bug? Why, that's when you hit terrain funny, or the edge of such, or the game just gets a wild hair up its ♥♥♥, and decides that you aren't touching ground. You can 'float' along, stuck in the falling animation and gaining digital momentum, until you manage to trigger either the same or a different bug, which forcibly helps you meet the ground directly under your boots, at terminal velocity. For me, it happens about once every hour. Could be more, could be less, and I often forget to save. That... is what makes this game unplayable in its alpha state for me. That one bug.
Does that mean I say the game sucks juevos grande? No, of course not! Like I said, I like the direction it's going. I like having to care for the suit and all your needs, (power, water, oxygen etc.) and feel it's a nice touch to differentiate it from other block-mining games, as well as giving the term 'SURVIVAL' its meaning. The enemies, once you find them, I couldn't help but laugh at when I glanced through the forums and first found their lairs. The crafting system, while not very intuitive or flashy, works well, (I'd recommend mentioning to people that turning on a forge while holding it will kill them... and a better guide of what to do to advance your tech wouldn't go amiss. Particularly iron. Maybe some sort of mission parameters and planned actions tab on the PDA, like proper space missions. Could even tie in the milestone achievements in-game to it.) As with all early-access games, especially alpha-builds, this thing needs work. A lot of work. But... if this all pans out right, I got a good feeling about it.
It's tough... but I'm gonna say I DO recommend the game, not for what it is now, but what it looks like the dev wants it to be.
