3rd Strike Makoto Main coming to this game as I heard about Olympia being based on her. How do I get started learning this game for her release?

I play some Smash so I'm familiar with the fundamental controls of platform fighters but I've only played couch casually. What's the best ways to get into Rivals of Aether 2 so that I'm ready for Olympia's release? I popped into training mode last night and had some fun with Maple and Orcina and the movement seems really complex and difficult.

This game is gorgeous and I love the art style btw!
