2D Animation?

So the wife and I want to do something for the quick Jam that Epic is holding for this weekend and we came up with an idea we really like.

I have negligible experience in Unreal but a ton in Unity so the basics shouldn’t be too hard but I have a question regarding how Animations are done in Paper 2D.

Do I have to use the flipbook with multiple sprites or can I use a form of animation for each piece and record the movement in a key frame manner? I’m used to using a system like this in Unity where each body part can be seperate sprites then I just move them as needed for the animation by keyframing and then playing back the animation gives me my desired result.
