Ok, I got the main idea. I downloaded the public apk from Itch and installed it both on my phone and a virtual machine. In both cases I couldn't reproduce your problem with the animation on werewolf or titwolf scenes across ~ 10 tries.
That's pretty strange problem since either the whole animation loads properly or there's something wrong with a preset and it doesn't load at all. At least in my experience. The only thing I can suggest to you - re-download the apk file and re-install it. I guess something could go wrong during the download process, especially if you used Wi-Fi.
