i got to the exit fairly easily, only thing was i'd only got like 2 coins and a bonus coin
anyway, after a fair few tries i'd discovered how to kill one UFO pretty easily but kept going wrong, my OH phoned me just as i'd started so i instinctively hid (but forgot to press pause

), answered the phone, and 3 minutes later when she'd finished rabbiting i'd still not been killed, went for a quick mooch and both flying saucers had disappeared
i'm sure i'd have done it easily if i'd had those 3 minutes back
ETA without trying to give a hint, i've done it now and got the gold star, and i didn't do it by killing both of the flying saucers, as it happened, that was just plain UN-lucky
