I try to give one thing I didn't like and one thing I liked. The thing I didn't like was that it lacked a tutorial or a better description on what's going on. I usually play fps games, so it was a real challenge to understand what's going on. The good thing is that once I did, I started having fun. I love that it is purely mechanical game, but you could work a bit more on the balancing stuff, specially in the early start. The theme is there, I like the story (or how did I get where I am and what's my goal) and overall good job! Keep up the good work!
