The world model's terrain get's in the way of some of the lighting, which prevents the player from being able to see the enemy. Very Ambitious, and cute however!
I like the cool swapping power. I feel like the 'good guy' is the meme of being in your base and killin all your dudes. Though, I suppose that does fit the popular FPS type of game where the hero kills legions of enemies.
Great background models! But the lack of a dog/drone detracts. Not sure how this was 'bad guy' related unless you're an evil drone who likes to carry the dog to his doom XD.
