The World's Hardest Game 3 Level 3 Walkthrough

DISCLAIMER:
This is neither a zero-death run, nor a speedrun of the game. I cut out the deaths just to show how to do each individual task. The progression of the death count throughout the walkthrough is meant to gauge how hard various parts of the game are, but results can and do vary significantly.

Now that we got that out of the way,
this video demonstrates how to complete Level 3 of The World's Hardest Game 3 and includes all the keys and all the paints.
