DuckTales: Remastered - Mount Vesuvius (Ep.7) FINALE-100%WALKTHROUGH(All Gems,Extreme Mode,No Death)

In this Walkthrough I'll complete the game collecting all the Gems and Treasures of each level on Extreme mode and without dying.
You can unlock the Extreme difficulty by completing the game on Hard difficulty. On the Extreme mode, differently from the Hard one, checkpoints in levels are limited, items and gems are changed and there are very few ice-creams and 1-UPS. The most important difference, though, is that if you lose all your lives, it's GAME OVER and you have to restart another game.
Mount Vesuvius (on Extreme Mode):
Total money= 1,776,000 $
Hidden treasure= None
Ice-creams= 3
1-UPS= 1
