I was thinking that I'd really love to see a list of new items/equipment, maybe a list of how charms have been changed, and maybe an indicator that something is exclusive to a character? I don't know if either of these are possible/plausible for you.
Toma in 600 AD has a lowercase I when he says "Can i trust this?" right before giving Crono and co the Pop (which should maybe be renamed to Toma's Ale, since he refers to it as an ale right after)
If I may make a suggestion, this Merman fight is awful, and I really think there needs to be something done about it, unless I am just really missing the point of that fight. I went in at Level 66, 64, 65 Crono, Frog, Magus. I couldn't do it at all, even with the Masamune 2 and Hero's badge. It felt mostly like the healing it did meant there was no way to kill it, and there being no way to run meant I had to load a save from a little bit back. I would love a warning, or the ability to run from the fight.
