Here is a debug cart to reach the sky fast:
1. grab the sword.
2.PRess select to go to level 2.
3. press select to skip level 2 platforming section
4. Run to the bottom room ( use UP+select or DOWN+select to use the ladder )
5. Run to the blue teleporter ball (( use UP+select or DOWN+select to use the teleporter...)
6.Go to the village, do the platforming to the sky. You will need to use the feather, a last minute jump to do it ( see video or ask )
