Dat's fair enough, I was mostly judging by the easier modes (I gots a lot of games to play), and it seemed like in most situations it was never worth the time trying to line up and throw Myon. Didn't realize the bullet blocking thing though, I guess I didn't pay much mind to what she would do passively since she floats around very freeform. It makes sense she'd be useful for higher level stuff, I was just playin' casual.
She's like the deku nuts of this game.
(oh looking at the other comments actually it looks like this mechanic could benefit from a tutorial adjustment to have small enemies with bullets as well. Since you have black and white projectiles with different properties, the tutorial was telling you that through the different color boxes you had to break, but having one more segment explaining you can do that to enemy bullets would've really cemented that imo, since it wasn't entirely clicking with some players that shiki's bullet colors were the same thing as the boxes. This is all just nitpicky anyway this game is heckin' great)
