Your music choices, mapping, and tone setting were great. Love those action sequences, as always. I don't know if the nonverbal communication really worked. I was a bit confused about what was going on.
Combat, especially battle #1 was too grindy. I actually quit and started over on easy because having to plow through so much HP by reading many, many skill descriptions was too overwhelming. For a jam, spending 5 minutes reading through skill descriptions and getting one's mind around them is just too much. I'd recommend maybe 4 skills per character, max in a first battle. Probably fewer.
I did play through and get an ending (not sure which), and I'm curious what choices could dictate the outcomes. I finished the game still unsure what happened, although there was a Harold, which is always a plus in my book.
