Are there like warp points in the dungeon to fast travel to? I realize opening up the shortcuts help, but should I be pressing on in a dungeon to get to some sort of warp point or stairs or something, or do I just use a Goho-M every time I need to leave?
The only warp spots are before bosses, and you can only start at the entrance of the furthest floor you've gotten to in every dungeon after leaving. My strategy has generally been to push through the floor until I hit a shortcut then goho-m out to save/heal.
