You're welcome! I love giving feedback to stuff :)
I wish you luck in trying to balance your idea for the battle system, and I am interested in getting to know this world's lore more (as I am with anything really).
On a different note, while it's completely different from Sea of Stars I higly advise playing The Messenger. Some of the best platforming i've ever had the pleasure to play. Sadly, I don't know anything about making stuff with RPGMaker so I can't help you with the popup idea
Have a nice day, and sorry for taking a while to reply :)
