Some extra interactions? I would like to hear some examples if that's possible. And feel free to offer your ideas, you notice what I don't from your player's perspective.
Anything to make it less static, really. Actually playing in the animation is leagues ahead on watching a video. Depending on the animation being able to change hand positions like touch actions, changing current animation stage, changing small parts of the animation on played scene, like position of a specific part or speed ect. Long story short, whatever you think will be possible :)
