Haha thank you very much! Yes that is definitely a challange and it's where a puzzle element comes in. You need to jump and throw the shield, and then recall it so you are able to kill all the 3 robots by recalling the shield. After learning this element, the next challange becomes easy.
yeah , i got that and got past them - its the area a bit further on where there is a gun at the top of the screen and you have to throw the shield to be able to jump up through the level - cant recall it fast enough to then defend against the bullets , then try to get a shot in against the gun - thats where im stuck !
