I've just pushed out an update that adds a rough 'Speed Run' mode which unlocks upon beating the game. Also Hard Core Mode now allows for players to access the Hero, Gear, and Skills screen from camp in between any stage, not just after boss fights. This will allow more down time as well as the ability to spec out for individual stages and bosses rather than needing to do so from the beginning of a zone. You still won't be able to head back to camp in the middle of a stage in Hard Core Mode - this is intended.
