i try to play with Creature an notice after working with After effects timeline(AE has perfect controls for 2d layer and bones transform) – creature timeline is not useful(like in programs from 90th), you need seriously work with creatureUI, also same type program like sprite and spine have better UI, thx
PS and pls create normal tutorial for UE, when you first create animation in creature(for example run, idle and jump…) and then setup those in unreal, without time warps
