Damn, the game idea is very nice! Frustrating to play (or maybe I missed some tactics?) but really nice and well implemented! Would seriously play again.
If you want, can eloborate a bit on what you found frustrating? We already heard while testing, that aiming accurately was really hard for some people, but we don't want to change that since it is such a core part of the game. Did you have anything else you think was to hard?
