The previous Avatar equip screen was merely the default equipment screen with slots removed. This new one organizes the avatars by rarity, and includes the faces in the mini status window.
The song featured here will be the theme for the title screen. Initially, I only chose it because some RPGs I liked have somber/depressing title themes as well. There's a story (lol) idea that'll work really well with this theme, so it turned out to be an unexpectedly solid choice.
After levelling up quite a bit in scripting, battles are now conducted without pauses when selecting cards. This was always bugging me, because this essentially let the player slow down time to react to anything. Now, attacks that start up in 20 frames do have to be reacted to in 20 frames.
