Just played the beta for like an hour. I really like it. I didn't find the face zoom thing and other effects as intrusive as I initially thought they looked. Don't know how to use him yet, but I really liked Diego from what I've played of him. Kind of wish you could dick around in a training room while waiting between matches.
Had two weird moments where I got stuck on the waiting screen, and one crash.
I really like the UI design on the menus (but I have crap taste so take that with a grain of salt).
Also like the ost, or at least the menu theme and the song that plays on the one stage.
