Well, I have two bad news to you:
1: The game is just about a costume party where the participants gain powers based on their costumes. So, nope, probably won't have any change of clothes. Not to mention that it is hand drawn pixel animations, which adds more to this.
2: The game probably won't lauch anymore since the devs got robbed by stupidity and ignorance of their director and now he's basically the only one working on the game. Which means that this demo and the one at Steam (Suits of Fate) are the closest of a game that we'll have about this project.
