Yukari Yakumo Boss Fight version 2.5

This is a remake of a remake of one of my very first Danmakufu projects from a few years ago. After tons of effort, playtesting, and several bouts of motivation loss, I'm proud to say that I'm finally satisfied with this script. I hope you enjoy it.
I call it "version 2.5" because this remake isn't a complete makeover of the previous one (named ver. 2.0 for obvious reasons, but I'm not posting that one here). However, several significant changes have still been made.
The script comes with the main boss fight (8 nonspells, 9 spell cards, and 1 survival spell card) in two difficulty settings, and a separate "Last Word" (a fixed difficulty survival card with infinite lives--the point is to try to get through with as few deaths as possible)
