Some tips. First do part with medals, good way to do this is make first levels on diamond level, trophies are pretty easy in my opinion, the hardest part is make worlds without deaths, i think the best way is to do worlds: 1(normal and advanced) 2 3 4 6. If you die while making the last part don't restart, Don't make medals and no deaths at the same run because it's almost impossible.
I know my english sucks but I hope it will help, Good luck ;)
