The settings used for this randomizer are meant to keep it relatively short (similar in length to the normal accessible rule set which adds in very few extra settings besides the basics) while adding a few extra randomized things to mix things up a bit more. The settings are:

Shopsanity (2 randomized items per shop)
Entrance randomizer (Dungeons only)
Boss Key keysanity (small keys still restricted to dungeons)*
Chest size matches contents (small chests will be unimportant items, big chests will be important items/ice traps)
*No boss key skips allowed
Also added in no logic for fun.

This excludes keysanity (small keys), randomized gold skulltulas, randomized scrubs, mixing songs in the item pool, and more entrance randomization, since those can all greatly extend the length. I do plan on doing another randomizer soon with ma random settings again.
