Help! Getting assets from apk

I am trying to get assets from app - unfortunately after decompiling apk assets are serialized/encrypted. Also I think not all assets are present (some are probably downloaded on runtime) Is there any option to get them? I know I can find them on internet but it's rather how to approach this topic.

Is it possible to get any assets from serializable data?Game is Horny Arcana (Not modded apk yet)
