Yes the game is in mono in that their is no sound panning for the fights.
The option at the top of episode mode is continue.
It's supposed to let you continue from where you left off, but so far; at least for me; it only starts the last episode you played from the beginning.
If you want to save your place you'll have to use the story control panel.
On ps4 press options when a story sceen is playing to reach this control panel.
The first option you're on is message speed. Press right twice to set it to instant.
This will make story sceens play out faster without skipping any voice work when autoread is on.
To save your place press up 4 times to go through back, story menu, reset to defaults, and finally, save.
Press X, then choose one of the 60 slots to save in.
Loading this save later is just like opening a book to a page you've bookmarked, so rmember what was said and the music that was playing when you last saved.
When you load a save and save again you'll be on that save so pres up to get to yes to overwrite once you select it.
You always be on new save if using the continue or when starting a new episode.
To load a save press R1 on the episode select menu.
During story sceens, press triangle to enable or disable autoread, hold r2 for fastforward, and press r1 then press up for yes to enable autoskip.
By default, text skip will only skip past text you've read before.
On the main menu, press left to get to options.
System is the first thing, but their isn't anything we need in their except vibration, which is the first option. Press left to turn it on.
Once done their, back out and press down to get to game options.
In here the only thing we need is difficulty, and that's what we're on, so press left to go to easy then beginner, or right to get to hard and hell.
If you need to reset to defaults go up twice and press X.
Two down from game options is sound options, and in here we need to go down twice, bypassing master and BGM volume to get to announcer, character voice, background and sound effects respectively.
Raise all these to max, remembering that the announcer and character voice settings play a sample that pauses a time before replaying, so fiddle around until you can get the sample to start playing and pressing right and left, making sure that the sample cuts off when pressing right, but restarts when pressing left.
In this way you can max out these settings.
Also, on the main menu, pressing right from the main list Crystal described will take you to online; in which their is only the online option, then to customize, then to options menus, then back to the first menu.
The customize menus don't have anything for us at all.
Once you complete the story mode, go into gallery, then press r1, then go right and press X to view the credits.
For some strange reason that still baffuls me, you'll get a psn trophy or steam accomplishment for doing this.
