I just played a bit of the bombing mission, thinking from the perspective of a new player, here are some notes so far:
The (L) Tag comment in the first battle is confusing, because you can't actually see the enemy names unless you know to push Select for the help text, and a new player doesn't know to do that.
And when you get that up, you see that they both have an (L), so they are both leaders with no minions, further confusion.
What does being a leader mean? No idea at this stage.
So perhaps have "Press Select to view enemy names and help text" or similar as the first message instead, and leave the Leader explanations for a later date.
Also "Night Shift (L) B" looks a bit strange, would look better as "(L) Night Shift B" imo.
Does it have to be a tag, why not just (Leader)?
"Some enemies heal others, like the Engineer" seems a bit unnecessary, as it will become obvious anyway.
Seeing what the enemy does, and adapting, is the fun part
Also this message comes up in a battle with just 2 engineers without the robot, and there is no healing, extra pointless.
I certainly like your idea of having these helper hints in battle though.
For example, the scorpion battle would be the perfect place to explain how to access the Defend option, which is pretty hidden away.
Since Defend would be perfect to use after the 'Search Scope' scorpion move.
After the scorpion battle, I was left without any Potions or Phoenix Downs, and too weak to obtain more.
A bit harsh for the intro section, having to restart the game. And I even got the 2 free potions from the guards at the start, which some players may have missed.
I did try to steal twice on the way down, but only got an 'Almost...' and a 'Grenade'.
Didn't realise I had to steal to survive.
Thanks for listening, I look forward to playing more of this when I have time
