Moving from The Legend to Armored Princess - what notable changes must i be aware of?

[john_crapper]

Played The legend 3 times, loved it, on to the sequel. I dont wana waste more than one game learning the mechanics before I shoot for a high-score, so Im hoping you will provide the tips and info needed.
I made 1607 points on Legend on my first Impossible (and 3-rd overall) game which took 14 game days, and I havent the foggiest how the one who did it in 6, actually made it.

Nevertheless, checking the high-score thread I am satisfied with what I achieved, so moving on. I understand the old way of retreating from battles and traveling just before 7 AM to save time is no longer usable ( thankfully), but I am sure the community has found other ways to minimize any high score hindrances.

And as the title suggests, I would appreciate being told about any other changes of significance from the first game
