interesting idea, but it gets really hard to coordinate with the opposite ship especially when it fires on the opposite direction. most of the time i've just used the normal ship to shoot, so the opposite ship feels more like a liability if anything. then again, i'm probably just bad... i liked the idea of the link between them becoming a laser wall that can kill the enemies though. overall, it's an interesting idea that would need to be a lot more fleshed out though :)
