Yeah, I understand. I normally never would have an idea this exotic for any C64 game, hence the C64 is not exactly known for it's widespread use of mouse controls in .... anything. It's GEOS, Eye of the Beholder is the first killer application game, and this right here, could be another, if it "feels just right". Twitch shooters (boomer shooters) are rare enough on 8 bit, but none of them, none whatsoever, have the kinds of controls that enable you to flick left, shoot a guard, flick right, react to a sound, shoot another guard... that sort of thing. ;)
