Store option isn't open in this build unfortunately.
Cross Assault still has the 'classic' music intact, however that mode is over so quick I wonder why it's there, really. Never noticed a music change during Cross Arts.
Music options - in this build there's really one, which turns on/off 'Climax settings' for music. When health is low you get some funky effects dropping the music into the background some more, almost like how an FPS might make all the sounds dim when you're about to die or whatever. You can turn this on or off.
Almost every stage does have multiple pieces of music, though... as the stage changes - either time of day or 'area' of the stage as you've seen - the music changes with it, which is a really nice touch. Other than that, not many options. Music unlocks in SSF4 were locked behind arcade completion which is impossible in this build, so who knows what awaits?
That said, I really do like the music in this game. Some have complained but I really don't agree. One nice touch is that depending on which 'side' character you win a match with you'll either get a Tekken theme or the SF4 theme playing as victory music.
In general the sound design is great. They've recorded a lot of dialogue for the characters that is dependent on context - Ken might annoyingly chastise himself "Ah, c'mon...!" if he whiffs a HP uppercut where in SF4 he would've just shouted Shoryuken. Juri, in particular, is great, where if you catch people in longer combos/moves she'll ask them how they like the pain, to scream harder etc. It's regular enough to be noticeable but it's not so frequent that it becomes annoying. It's a nice touch and evolution from SF4, which only had this in Arcade mode and very infrequently.
Also good is the recordings for calling different people in. It won't just be names being shouted (though you will get that) - if things are going well Cammy might yell at her partner to "Keep up the pace," while if things are going poorly she might state they're "Changing to plan B" as she tags. I did laugh out loud as Balrog screamed "get off your ass!" to Ibuki to tag her in.
Voice options - in this build it defaults to "Cross Style" which is all SF characters in Japanese and then Tekken characters in whatever their native tongue is. This'll probably be all SF characters in English and Tekken characters in their natural language in a final localized build for the US/EU.
The other options are English/Japanese - which means you can have the Tekken cast, even folks like Kazuya, in English. Every character can have their language changed independently too other than King and Kuma, who obviously don't speak at all.
The build has character intros, but no endings - after a few fights you get a 'thank you for playing'. The story advances in a material way with set teams - after fight dialogue (text only) has the teams talking about where they're headed, Shadaloo, etc etc, advancing a little with each fight. Rival battles aren't in this version.
In Arcade Mode you only fight set teams - Ryu/Ken, Kazuya/Nina etc. If you pick a non-set team to fight with that eliminates those characters' teams from appearing and means you only get a generic story of all the Pandora stuff. No CG intro on this build, not even any of the already released ones. They don't appear to be in this build anywhere, but again, it's not finished - it was burned in early Jan.
