I have news!
I was able to grab the demo on xbox one, and it's not actually that hard to do at all. Hong Kong store did the trick. Change location and keep the rest at English to keep Narrator. The rest should be fairly easy if you know where to find demos, and you might even be able to search.
Here are some of my findings, although keep in mind, this is going to be rough because I haven't really had the chance to get sighted help or anything, this was more of a test run. I still have some time left but probably not that much out of my 2 hours, perhaps I have between 30 and 50 minutes left.
Once in the main menu with music, for the first time there's a dialogue that lets you go up and down but I just tapped a to dismiss it, and then you end up in a left right menu. The thing to note is that a lot of this menu is voiced when you press a on the initial options, and this includes initial submenus, in the demo you'e got practice, battle and options, and in practice you've got training which is your practice mode, and tutorial which might be called dojo here, I'm not too sure, and in battle you've got vs. If you click an option that's not available you get a dialogue that you can just dismiss. The voice is in Japanese but he's sort of saying it in English as well. Then, today I discovered something even cooler, this left/right menu does not wrap at all, including submenus. Any up/down menu will wrap.
To get to audio options, go all the way to the left to find, well, options.
Then once in that menu, go all the way to the left but this time, tap right once. You should be in the sound options.
I only know the first two options. The first one seems to be the equivalent of a master volume, so that will turn down absolutely everything. The option below that is music. It's a slow process to turn it down, slower than KI but it's also perfectly fine, very good for fine tuning. When you're done, press b, then tap up twice and press a. You might be able to do this by tapping down once and pressing a. Pressing a, without doing this, will take you back to the sound options and plunk you somewhere I don't remember where, maybe on the last option you adjusted, maybe on master volume, I can not remember. From the b menu, Pressing up once, and a, will not save your changes and I think just take you back to the main left/right options menu without saving.
Entering vs mode is a little odd. You find battle, go to vs, and then, if you want to play against cpu, you have to get your other controller (p2), tap right on it, and press a. Then use the controller that you would normally use to play. If you just tap a without doing this, you get into a two-player vs battle. I don't know why they couldn't use one of those dialogues where you tap left for player one and right for player two, and have the center option be for both, but there it is. It's a bit odd.
What do I think?
I can seriously, seriously highly recommend this especially for those new to fighting games believe it or not. There's footsteps, you can hear when people are running in, you can hear when people jump, and what makes this game so great for beginners is the slower pace. You've got quarter circle motions and dragon punch motions but you've not really got combos or anything like that, when Assault said it was slow, he really did mean that. Seriously, this is as methodicle as it gets.
I was quite excited before. I am now over the edge excited. Everyone needs to play this game at the very least once, with the music turned down a bit so you can hear the footsteps. Rolling also has a sound. I genuinely can't believe I'm saying this, but I can safely say that we're on to a winner here, depending, of course, on how easy it is to go into an online match, which you can not test in the beta.
I rate this demo four out of five samurai swords.
