Yeah was worried Mac is broken. I just dragged the game folder from the PC version over, as I couldn't rebuild it myself. I'll add a warning that its most likely broken.
Could you delete the live2D folder in /game? And see if that fixes it.
The update is indeed badly rewritten chapter from some other game that has nothing to with witch cartoon. it barely has anything to do with the witch girls and consequently barely contributes to the game.
