"Holy Shield!" If this were an in-person Jam, you can bet I'd be using that as a meme!
I played a DS game like this once; loved it, loved this! One thing you're missing though: context. If you were going to take this further, I'd want some visuals for the people in my party and the monster they were fighting. At the moment, I'm managing bars and checking data. I'd prefer to be glancing at a piece of artwork that showed the same information.
