The best way I feel like I can sum up the game’s overall motif would be: shoot “2001: A Space Odyssey” in the style of “Paranormal Activity” where you take control of “HAL 9000”.
Puzzles are fairly straight forward and while the game won't hold your hand during any of them, they kind of boil down to just instruction following.
Audio design is fantastic. The game really does a great job of conveying the sense of deathly quiet isolation in the seemingly limitless emptiness of outer space while also dealing with an impending doom. Everything from the crackly radio communications to the sounds of airlock decompression all give off the expected muted sounds that make the whole thing feel authentic.
I'd give it a rating of Good/Great.
