I decided to give this another go and I made it in a quite good amount of time for the size of this quest. The only things missing (on purpose): Svalbard Temple Map (saved me 5 minutes), Kali Beach Key (during Level 3, saved me another 5 minutes and the super secret key compensated for it), Master Dome (skipped entirely, saved 20 minutes or more, originally intended to be played after getting the Bomberang on Last Isle), and eventually Last Isle itself.
The reason why I didn't get to Last Isle after beating Morlach was the lack of a save point for the last escape and I decided to not redo the entire final boss battle since I was pretty tired after a full day of playing this quest (roughly 13 hours playtime, about 10 hours on video). - https://www.youtube....Kzbyoh0OX8fxkAc
