I've been playing around with it. The first couple tutorial levels are pretty sedate geometry puzzles. Then you hit the level where they start shooting back and everything changes. Then it becomes about efficiently planning your order of operations as well as the geometry. It kinda reminded me of those food prep games where you had to quickly hop between stations and keep all your plates spinning before the timer runs down. I thought I was doing well on my first crack at it when I knocked out 2 of the counter-battery units in quick succession but the third one got me just as I was rotating my turret for my next shot.
