Thanks for playing! I didn't think about the symmetry part of it too much, but maybe having them be palettes swaps would make it easier to tell which piece is which. I guess I thought it'd be weird if she was also fighting against magical girls story wise, but doppelganger monsters are fairly common too. I'll consider this some more. That's a good idea about the dialogue though, having little scenes in between levels or when you pick characters would be a good way to add a lot of personality.
AI was tough to balance, and there's still a lot of improvement I want to be made. I think it prioritizes the major pieces too much, so a lot of times the pawns will just be awkwardly sitting in their starting positions the whole game...
