You can already do the sprite anims! If you go to the character menu, where you add the actors for your game, once you add their name and text colour, the image can be added below - you can add individual expression images, and sprites-sets.
The sprites-set is just as individual pictures, but you can pick the number of columns and rows and do it like a rotascope sheet too, bit like in RPGMaker and RPGPaperMaker.
From what I remember, the 2.0 release will have a 3D add included, but more info is in the DevLog above. Live 2D I'm not sure of.
