The first scene made it very obvious what kind of game this was. Some issues exist.
Definitely feel like the transformation scenes could have been done better as well. Either by animating it or by making them feel more alive and flowing instead of just fitting them in place.
There are really just a lot of fights. It seemed like you could have adjusted them for fewer, but harder fights. You can end up fighting back to back and end up with a relatively black background for fights fairly easily.
Lots of buildings to block your view with no real way to tell where you and the enemies are.
Not sure why you were let go so easily when you haven't really been useful in years. Why did the doll suddenly power up your badge? Might want to add some extra lighting when the doll flashes to make it more obvious what the doll does. By that, I mean fix the lighting so that it is easier to see the badge during the scene. Right now it looks like the light is just an add white instead of add color so it just looks like someone messed with the brightness and contrast really poorly.
If you talk to the third girl first, the game just breaks. Stopped there.
Synchronization never seemed to work. I tried using all of them and two of them. Neither did anything and just wasted a turn.
Bravely Default's brave system is a bit broken for a lot of games, but autobattle works fine here.
For being experienced, your party starts off low level. This is something some games do, but it can feel a bit unnatural without a reason. Might have been more natural if you started off strong enough to just wipe out groups without a problem, then became weaker due to years of inactivity.
Seems odd how a few of those mechs cause a problem when they are so easy to defeat. Even with one hero down, it felt like you could have kept going. Felt a bit forced that they just quit after one problem.
