it was fun! a very good take on the theme :)
a couple of things i would probably wish for:
- a bit more response from my actions, maybe sound or sometning else: first time i disn't understand which unit i chose, cause i couldn't see that anything changes when i click.
- the shooting sound becomes a bit repetitive, maybe add some music that would accompany it and reduce monotony?
apart from that, i liked the game :) the winning screen is epic!
