This is a cool start! I love the idea of a magical girl boardgame. The graphics work well, and I especially like the depth of field effect. Really highlights the "miniature" feel of the game.
Without a tutorial, it is a little confusing at first, but I think I made sense of most of it by the end. I didn't really understand the "flux" element. I did one full run, with the pink character winning.
One thing happened a few times that was either a mechanic I didn't understand, or a bug. A few times, when moving, the character would seem to teleport instantly to a distant place on the board. It's possible that was intended, but I couldn't really tell.
I hope you keep working on this! An AI mode would be fun to play against.
