Fun, and the pictures/designs are good. It can be challenging manipulating the pieces, but I think that's part of what makes the game different and interesting. I think it's a bit easy and could do with more levels; the last level is far too easy to finish with - it should build up to a big challenge. But certainly a pleasant little diversion.
It's a bit boring. Needs more upgrades for the units and variety in the levels: it's just screen after screen of identical gameplay. The things you can buy are all really boring as well.
