This. Was. Awesome!
When I first saw the stats I was worried that it was going to use an over-complicated D&D-like stat system, but I was pleasantly surprised with your simple, yet effective system (although some stats were clearly better than others).
This adventure was short, to the point, and there was a lot packed in. My only critique was that after a while the battles started feeling tedious. However, that might be because I got lost a lot of the time and ran into guards at the same area repeatedly (which I suppose is appropriate for the theme).
Your use of 'Key' was great; not only was the powersuit the key to winning the war, but it was key to blasting your way out of the base. I noticed you also had an electric key in the story; there were a lot of keys.
I liked the way you layered the paragraphs to handle 3, 2, or 1 guards at a time, and getting the powersuit felt AMAZING.
10 out of 10 - would powersuit again!
