Very pleasantly surprised a few hours in. I was mostly expecting just a rehash of Hyrule Warriors with a BotW aesthetic, but the core combat loop was definitely significantly tweaked and improved upon once you get used to it, and a whole lot of extras thrown on for good measure. Only have Link, Impa, Zelda, and Mipha so far, and overall I'd say that they're all fun, though I'd rank Zelda at the bottom as a playable character combat-wise at the moment.
Only stopped due to my battery hitting 5%. Easy time sink game.
