To be in “Go Mode” means that you have fulfilled all of the requirements towards at least one method of finishing the game and may pursue that path at any time. Standard Jets of Time has three Go Modes: Tyrano Lair to Ocean Palace, Death Peak to Black Omen, and Magus's Castle to Ocean Palace.

A “jet seed” is a seed in which Go Mode is achieved far sooner than typical. They can be completed very quickly, but are often dangerous as the player may not have had time to accrue items and protective gear.
