The controls in Onslaught are great, I don't know what he's talking about. As for "refocussing", just point at what you want to shoot and shoot. It works, even if the target is moving on screen(and you follow it to the centre) it's still perfectly intuitive.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
