As far as gameplay style and moves are concerned, here are the deets straight from the devs:
• Double moves around the field as a quivering eldritch horror, and transforms into other characters for most attacks
• While Double may use frames of animation from other characters, many of the attacks are “remixes” of the moves she’s copying
• Even though she transforms into other characters for them, some of the moves are exclusive to Double: several moves that didn’t make the cut on the original character made it into Double.
