What if I don't collect all the pieces? I missed that part earlier. I just couldn't do.
<edited, the damn forum doesn't allow me leave things the way I want>
I went by killing them in the given order. Now I got that I've kill 5th one by jumping on its head and at the same time I'd get up on the upper platform to kill the 6th one. But the jump is not high enough in however way I do it. Any tips anyone? (Only this piece is left in this world)
Well I moved on and now I'm stuck here. (World 5, stage3)
How do I get that part?
