Here are my thoughts about this game too, as I also played it for judging during the finals.
Overall it is an interesting idea, and the game plays like a battle arena type game. I did find the party a tad odd and I didn't really care for one of the characters in the end in our party. I think it was probably a time limit thing though as you had to make it a one hour game which doesn't really give you a lot of time to get to know them well.
I do feel one battle was a little cheap due to the enemy stun locking you often. I didn't write down which battle it was sadly in my notes. I do wish there was a revive item or a better HP restoring system though as I felt healing was a little limited. Granted heal to full before every battle (well except for one which I will not post due to spoilers) does affect that but a backup way to revive at least would help just in case bad RNG messed up a battle.
I do hope though you expand on this idea at some point. And congrats on getting to the finals of the IGMC!
