Saint_Voice sup?
I finally got the time to play and test, everything looks fine, all gamebreaking bugs (at least on linux they are gamebreaking) I've found iare due file naming conventions, it seems that windows is a little more lax with these but it would be good to standardize your naming scheme, its a good habit, I would advice using snake_case.
List of files:
www/img/menus/faces/faces3/Actor_1.png should be www/img/menus/faces/faces3/actor_1.png or you can change the way its called in code
In the www/live2d folder because the way live2d works all files (cdi3.json, physics3.json, and .moc3) must have the exact name, folder with this problem:
74_Maria_Broom
71_Maria_Bath
44_Angie_Puente
101_Kiyoko_Suck
on www/live2d/03_Marjo_Sleeping1/Motions/
MC_Marjo Sleep.motion3.json has a space character it should be MC_Marjo_Sleep.motion3.json
So basically everything is runs fine after these changes, so just be a little more careful with filenames, keep the great work pura vida.
