Thanks for sharing the latest version, and congrats on all the big life events!
I just finished the Tower of Zot and I'm still having a blast with the game. Honestly this might be the best version of FFIV I've tried, and there's a lot of versions out there lol. The difficulty seems to have dropped off a little once I hit Troia, but that could be because I ransacked Eblan and got the Moonbeam and Earth weapons.
I love how many items are now useful as their own usable spells. I think Moonbeam and Earth might be a little too overpowered for now (I've been spamming them basically non-stop without consequence). Maybe some enemies need more magic-based counters to shut down that tactic from being used every battle?
It's been harsh with both Rosa and Tellah being primary spell healers and having such low Agility. Seems to take forever for their turns to come up, even after casting Slow on the enemy or boss. Potions are still a full-heal for me so it's not the worst thing to deal with but it can make squeezing in some tactical buffs or debuffs pretty difficult early in the battle.
Overall though I'm super happy with your work and ideas of balance so far.
