Great idea and the artwork is very high quality! Great use of AI. It was often tricky going back to hit the switches once the gunner had moved off screen (maybe the camera should just follow your character?) - this was also an issue for the boss battle, where the gunner sat so low on the screen I could only see the very edges of the boss's guns and shield. I also wonder whether it would be okay to make the two characters not collide with each other? On a few occasions I couldn't get up in front in time to protect the gunner :( Lots of fun and personality in this, it's an idea I'd love to see some expansion on ^_^
