As a strategy game it felt like it ended a little too quickly. And might be too abstract to really understand the consequences of your choices. I am really intrigued by the almost boiled down RTS direction it has going on though. My strategy started somewhat sound, in that I would place the initial orbs to hold a line of defense as far out as possible. But then it rapidly devolved into spam clicking just to try and get down orbs wherever I could, behind the ones breaking. Perhaps I did not take enough time to try and understand the systems better.
Certainly an interesting lil' experience. Has a good level of polish to it. Keep up the good work.
