Ohhhhhh my god. This is amazing.
First, my thoughts on the gameplay: RTS is one of the game genres I am pretty neutral about in general. It's pretty fun to play, but it gets quite hard and personally I'd prefer if the new mechanics came in less slowly. Definitely one of the better RTS games I've played, but the difficulty was a bit much for me.
But the STORY.
Ohhh man, the STORY.
This is an amazing work of science-fiction horror, with beautiful language, amazing imagery, and truly powerful themes. It's just... Well, unthinkable how powerful this narrative is. I've read it over a few times, and it's just so powerful to read. Get's me to almost cry nearly every time. The parable of loving someone you feel you cannot relate to. The depths of obsession. The sacrifices made to ensure safety. Honestly, it's one of the best horror stories I've ever read (and that's saying something -- I read quite a lot)! This will definitely impact my writing styles, how I look at stories and storytelling, and possibly how I look at life. I congratulate you on writing something so amazing.
