Some of the movies don't play, in "label w2d7s1" (script.rpy around line 21950).
Somehow a superfluous dot got added to the file paths, it should be
"
play movie "anim/w2d7s1-1.webm" loop
"
instead of
"
play movie "anim/w2d7s1-1.webm." loop
"
(and the other animations in this scene, altogether 6 or so)
Glorious ride so far, the game is fun!
