Skip 1:

Fortunately the game doesn't check that both characters have to be up top, really easy and consistent skip. Should be self explanatory on what to do.

Skip 2:

Game is weird, you need to hit the second spirit before it removes part of the death barrier to make the big fall possible. Skips the really obnoxious part of Forest and is super consistent once you get the skip down. On the last ledge, I'm going near the edge but not exactly near the ledge and then pressing and holding A and right at the same time till she falls to the lower platform. Saves about 40-50 seconds over doing this part optimally.
