Charming, but shallow, this tedious strategy game simply doesn't have that much there.
The art design is charming, and so are the animations and sounds but the meat and potatoes of the gameplay simply loses its appeal far too quickly.
On the plus side, the base building mechanics are solid, and traps are fun, but there is no differentiation between islands, and you are often restricted in size. Research can grant you more expensive but more space efficient versions of existing technology, but deleting old building plans within the confines of limited space and starting over is a real pain.
Minion AI is atrocious, which I suppose is intentional, but it is also lazy developing. your own minions will constantly die in your traps, and minions make no distinction between themselves as far as their role goes. Your ever so valuable third tier minions are just as likely to stumble into the gas pit attempting to kill an intruder in hand to hand combat and die as a plain worker. And I don't even want to start talking about how repetitive the evil missions are.
These are just a sampling of the problems with the game. Overall, I would say it is a fun little game that is not worth more than a couple dollars.
