How animation is being done in this game?

[Laperen]

I am wondering how this game might be handling the character animations in the game. It's a mini-game in ZZZ.

Here is how they are moving about and emoting in their room.

And how they are in dialogue

Here is the link to the game for anyone who might need to see the debug info.
