This game is pretty cool. I'd love to see more of your boss ideas. Couple things: a little more feedback on the attacks would be better. I found myself staring at the health bar most of the time to tell if I was landing hits. Second, the boss with the turrets heals way too fast. He was kind of a pain. Maybe I just missed something. Third, some kind of message to say you won would be nice. After beating the second boss I just wandered around a bit.
