I can absolutely tell you put a lot of work into your characters and fleshing out the world, I was really getting into it. I enjoyed the artstyle as well, not to mention "nuns with guns" is an unbeatable trope :)
Personally, I'm not huge on turn-based RPGs, even real-time ones (I made a speedrunner FPS for heck's sake), so take the following with a grain of salt! I messed around with the dummy a bit and gave the Hellioness my best college try, but the system just didn't hit me hard enough in the hummingbird attention span to compel me to learn how to use it. I feel like an info screen to read up on all the characters' abilities outside of combat, or even a pause ability during combat, would have compelled me to try a bit longer.
