Interesting concept, although in a way not immediately intuitive. First time playing through I thought that the game was just an endless grind with how little damage your bullets do.
Later I realized how you'd go about winning and although this game titles itself a strategy, there's only one way to win, which is to just stack turrets up close to the enemy base right at the start.
I really wish you'd fully explore the potential a simple strategy game like this can have, but with this being very shallow and one level long, I can't particularly say this is a game I'll remember. However, I think you could if you put the time in!
