Hello!
Sadly, We can't disable the animation. If we do this, the characters will be emotionless one pose poker face static sprites and this will add bugs and crashes because engine will search for animation files. Disabling animation - mean we will need to create the game one more time + drawing all the emotions and poses + alter all the backgrounds.
I suggest you to watch YouTube series by marvelous Aromie with the game "let's play"
