Moriko, it's great to see you're back! The new model looks really cool!
That bug with the fourth saint...wow...I have no idea of what happened hahaha, but I'm guessing you played the first version I uploaded. The latest update fixed some boss battles and made them less tedious.
Barbara's mother was actually a last minute addition (originally, she was supposed to be a nameless maiden in Barbathiel's manor), and the idea of naming her, her saying nothing at all and having not much importance, was more of a joke on my part, but I reckon she could have been a more developed character.
I agree with what you said about the exorcist/soldier being underused. Originally, I thought about giving him a solo segment and making him fight another boss, but we were kinda running out of time and so he was "robbed" of his final moment to shine. On the other hand, he was actually supposed to die, so I guess sparing him by the end was an apologize to the character.
I reckon the Julia clone kinda feels like a Mary Sue at times, unlike Alesa. I'll admit at times I wasn't sure of how to write her/evolve her character and I was more focused on the other characters (I loved writing the evil messiah and the creepy Barbathiel). I actually had an idea to focus on the other powers (pyrokinesis, cryokinesis, etc), similar to the one you mentioned, but yeah, time constraints and it might have been a bit too demanding. This had to be released on that exact date (October 1) so some extra details had to be discarded.
NewmoniaCute's definitely the star of this saga and I'm still amazed by her designs, specially the saints. I also wanted their boss fights to be a throwback to The Sakabashira Game (and Barbathiel even has the same mechanic as the final boss of The Sakabashira Game, hitting crystals while there's a countdown).
Overall I'm really happy with the results, considering this started as a little experimental game and it was the first episodic game I've ever made, but there are definitely things that I can improve and implement in future projects.
As always, thank you so much for playing and for your feedback Moriko!
