DuckTales: Remastered/Walkthrough

Selecting a difficulty
DuckTales: Remastered consists of four different difficulty levels. Collecting all Heart Containers on Easy and Medium earns you an achievement/trophy, as does beating the game on Hard and Extreme, so each difficulty has its benefits in collecting achievements/trophies. However, the experience varies greatly between difficulties, so choose carefully; there's no shame in starting with Easy in order to become adjusted with the game's mechanics, as enemy patterns and environment quirks can prove frustrating for the inexperienced player. Take note that Extreme is only unlocked once the game has been beaten on Hard. Below is a list of differences between difficulties.

Game progression
Before you can even access the level select hub at McDuck Manor, you must clear the game's introductory level, the ../Money Bin/. While this level has the elements of a tutorial, it should not be underestimated, as dangerous hazards throughout the level and the boss fight at the very end of it can prove tricky. Defeating the Money Bin's boss leads Scrooge to the level select, allowing you to choose which level you play next. Try each level out to see which is easiest for you, as boss difficulty is all a matter of subjectivity (though there is a trick to the Moon's boss that makes it surprisingly painless).

Starting out with the easiest level will allow you to collect a Heart Container for the next level, and so on. On Hard and Extreme, it is recommended that you start with Transylvania or the Himalayas, as these are the only stages where Heart Containers can be found.

Once all stages in the level select are cleared, the ../Finale/ will be unlocked. Completion of the Finale allows all prior stages, including the Money Bin, to be replayed for extra money. That money can then be spent on artwork or music in the Gallery (accessed by entering the door on the far left of the room), and all previously collected treasures can be visited in the money bin (through the door at the back of the room, complete with a diving board inside).
