I don't get it, but nice work

I am sorry, but this game didn't work for me. I understand that the idea is to search an optimum build order, but this mechanic somehow didn't appeal to me in that context. Unless I missed something, it's just shooting one target and it gets old quick.

I'll acknowledge that the game is well made graphics and sound wise. great ambiance, so even though I didn't like it, I'll give a good grade.
