Got the game stuck by triggering a level 3 Blockbuster during the frames in which Fukua was turned around due to her throw clone clipping the opponent into her during its hit animation. I suppose this would be common behaviour among all of the moves that cause this.
I think you shouldn't leave this "feature" in this limbo state where it's at the same time both unintended and exploitable. I know the game runs on a modified version of the other SkullGirls game, but why keep the turning around a feature at all if we aren't supposed to use it?
