First off, lovely art and aesthetics! It looks and sounds amazing. (My one nitpick.... the character VOX is pretty cool at first, but starts to grate on my ears after awhile... maybe have those only play sometimes, not everytime? To be fair, Persona games have this issue too, so for a jam game it's hardly a problem.)
The combat is pretty solid. I could have used a tutorial, as at first I didn't understand why I was missing enemies. Once I released that you had to target rows it made sense. The AP/Magical system is a little slow for my taste, felt like I was always running out of power. I'm not sure what Venom Kiss was supposed to do, it seemed like all she could do was heal herself. In the screenshots I see re-ordered players, but I didn't figure out how to move them in my playthrough. I also wish it would default to targeting an occupied row. I'd regularly accidentally hit nothing.
I made it three levels deep, but kept getting defeated in the third area. Still, a very impressive game. Nice work!
