There are a number of creative and unique aspects to this game. It's impressive!
The intro was good. Not too long, animations to compliment the narration, and sets the scene well.
The battle system has a lot going for it. You explained it well at the beginning, and overall it makes sense. I'm torn between siding with other reviewers, who want a "guard" or "wait" command, and keeping it the way it is, because managing and planning your attacks is part of the challenge.
A couple of things I didn't like were the interactive map elements and the final battle. Asking "do you want to use the rope" or "do you want to cross the bridge" whenever a character gets near those objects was so annoying, and the slow move speed didn't help things, either.
The final battle was WAY TOO LONG. Even the turn counter started saying "Turn too many."😃 Also, a minor annoyance: trying to select characters in battle is a little unintuitive. Something you might want to optimize in the future.
Criticisms aside, I enjoyed playing this game and feel that it's a noteworthy entry in this jam. Good job!
