A1: The last bit you get him in the heart but the start the bit is easy just keep jumping over the staff if he slides it across the floor

A2: On his first life you have to get the blue can and kill his force feild straight after you do that you get the red can and hit him until the force field pops up again keep on doing that until he dies trust me I clocked it lots of times.
on his second life he spaps the wand and sticks the orb in his back and goes humoungus and the platform go big he hit you on the platform and you have to go half way round to get the blue can go back to the claws swing and get the red can e will stick his fist in the platform and you clime up it and keep hiting the orb until he chucks you off repeat it until he dies.
on his third life he starts flying and the platforms float at the bottom there are three platforms two are small one is big on the big one there is a yellow can you fly up to the platform that has another yellow un till you get the orange can WARNING the platforms disapear.
on his fourth life he grows wings and glowbox comes with the flying thing and you go up in the clouds and he comes behind you grab the gun and shoot down his forcefeild twice and then shoot his orb befor he hits you when he goes to the ground and you think he is dead but he is not he heals himself by sending out hoodlum so you have to stop hoodlums from getting to him you shoot out bombs to kill the hoodlums and repeat
