Concerning the UFO it has to be the rapid fire button that must be pressed 12 or 24 times (you may have to set rapid fire in the option menu). I got the robot now but I still haven't seen it. However, he is sitting on a random block in the third row - just try to shoot the whole row forward. After 5 seconds it should have popped. Age 23 now with a slighty lower score - so I guess it does not depend on the score - you probably have to be good in every game so if you got Level 15 in one game and level 95 in another 55 in each would have been better.
