The intro with the story was very cool, and I liked the aesthetic feel of the game. I also love tactical combat games, so it was quite fun, though I'd have liked to have seen some more options for tactical decisions (e.g. as someone else noted, having a cover system where I can hold cover without removing my ability to shoot would have been nice).
I don't know if I was just lucky, but it didn't feel like the chance to hit percentages were accurate. I eventually got to the point where I took any shot that wasn't 0%, and hit most of the time, even on 5% hits. So the strategy very quickly became bundling up my guys and focusing down anyone coming into range. (Interestingly, it made the "first" level with only three enemies harder, since I only had two guys.)
Anyway, a cool game!
