I really like the style of the game: it seems like a game that a child would make with pen and paper, and I mean it in the most positive way. The problem with this is that the lack of animation really makes it difficult to understand what's happening most of the time. The sounds help, but they're not enough. Also, once I have a couple of enemy units on one of mine, I couldn't click it.
It needs polishing but it's really unique, great job!
