Drawn To Life Requests

I need the icy lake level in world 1. P.S i only got the game 2 days ago, so don't grill me,k?

how do you beat the last boss?????

I need a walkthrough for the platforms/lever at the end of the Gearworks level.

In the forest world on stage three gearworks I have came across a switch that I think I have to flip to make the red blue and green platforms work but I can't find out how to make it flip.
