thx! :)
I wandered a bit deep into the rabbit hole of animation; for Act IV I cheated mercilessly, then got cocky, and made act V's animation all from scratch. It was... a lot of work. Many square pegs were hammered into round holes. The end result has a million ways it could be improved, but at some point I needed to admit to myself that I'm a programmer, not an animator, and get on with the story.
