I really like the concept of this game but I think it's only interesting once you get to Myadas. One way to make that boss even more interesting is by not letting concentration/wrath stack. That means the player would have to use concentration plus an attack that affects one or two other collumns meaning they would need to get those first two down to the same number as the other.
I also think everything should be sped up like 5x. That would make this super enjoyable. And I'm not sure the commentary is necessary. I think it would be a lot cooler if the player figured it out by playing.
Overall love the concept and wanted to keep playing for more complexity.
