I could not figure out how my drones attacks or the enemy's attacks worked. Also, the controls say that spacebar will execute plan, but that did not work for me. However, I really liked the user interface for picking which map (stage?) to do, and the top-down view in the lower right is a great touch. The way that the stage seems to build on what you did before is also neat. I think I would love to play this game if I better understood the way it works.
