Very good mod, Martlet is fun as hell to play as and her voice lines are great, probably my only complaint is that with proper practice, some of her abilities can be TOO powerful. Long Jump out of Ground Pound allows you to essentially triangle jump, meaning you can easily wall jump up to the castle roof. It'd be nice if there was some way to balance her incredible aerial options by making her ground game worse, but all in all I find it hard to want to switch off of her because of all the crazy things she can do with enough practice.
Also Ceroba would definitely be nice, maybe North Star, too?
