For these “Finish the main path” achievements, all you need to do is complete each level and progress through a given area, then complete the final level of that area. You will know it is the final level because there is a rainbow like cloud around the circle. And the same applies here, just complete the last level. Don’t worry about completing challenges, or setting high scores, or flawless full combo runs, just complete the levels as you can always replay them later on.
