Fantastic remake, Talos. Here, have some feedback~
Pattern 01: Thou hast committed a sin, for there are no arrows which split into bullets! The successive blue and green waves of arrows give me Futo impressions, which is not necessarily a bad thing. The green arrows seem almost too sparse and slow compared to the almost literal explosion of light that follows. A suggestion would be increasing their speed, so the player does not get to just sit still when the rotating pattern starts.
Hermit Sign "Guse Soul": You might want to make the desires bomb-resistant, primarily because deleting them prematurely makes the whole Spell Card completely awkward by spawning the bullets in the upper-left corner of the screen (xD), and also because they are the main component of the attack, after all.
Pattern 02: A conceptual recycle of the first pattern? I feel as if it could use a bit more distinction from Miko's opener as-is, though.
Discernment "Tenth Articles": I like this recreation of Colors of Twelve Levels. I found it a bit too easy considering you basically had to hug the bottom of the screen and wait until her life depleted completely. As a more aesthetic-wise comment than anything else, the combination of colors used seems a bit too random and/or incompatible (if that makes sense to you). It would be much more appealing visually if it had a gradient color scale as the lines go, or something like that~
Pattern 03: No real complaints here, the nonspell is quite good. You could force the player to move around a little more using the sine wave of green arrows, and the bursts at the end are decently intimidating.
Hermit Sign "Land of the New Sun": Somehow, this seems somewhat empty to me. I really like how the whole pattern twists and resolves, but I would add a secondary attack or direct addition to the base pattern to spice it up. Perhaps make it slightly more dense (Even though I know how deceptively big the desires' hitboxes are, or maybe that was just the shotsheet I used ^^;).
Pattern 04: So there WERE splitting arrows! I would increase the delay between the opening wave and the dot-splitting one, at least so that both are immediately successive and the only "breathing space", to say, would be the time before Miko begins the attack again.
Light Sign "Fatal Flash": Oh my god I love this. The pattern is beautiful, it is reminiscent enough of Guse Flash both in visuals and in playstyle, and makes excellent use of speed plus the intimidation factor.
Pattern 05: Surprisingly for a reinterpretation of Miko's fourth nonspell, this is quite easy to read, at least for me. The next subphase even more so, considering both the blue and red knives more or less overlap in their trajectories. Still, it is a pretty good pattern, too.
Secret Treasure "Chandelier of Ikaruga-dera:" Another very good reinterpretation of one of Miko's original Spell Cards. Aesthetically, I would personally make use of fireball bullets (or glowing ones overall) to set the theme. Pattern-wise, I think you should start firing the medium orbs (that only appear in the red wave) at the beginning too, or speed the whole wave-firing process slightly to eliminate the gaps in which nothing (bullet-dodging wise) is happening in the Spell Card.
Pattern 06: Oooh, very good pattern here. I would at least increase the speed of the trail-effect bullets, they are too easy to read otherwise, especially in the first subphase.
Discernment "Ray of Ninth Articles" This is quite appealing and challenging, and I like that. I figure you should fire the trail bullets with the first iteration of the attack as well, not just the second and onwards~
"Desire Cycle" I love this as well. Between dodging the amulets and those trail-effect bullets I seriously cannot stop drooling at, I feel this is reasonably difficult to be a final spell. The timeout phase if pretty wicked as well. xD
I definitely enjoyed playing this. I think this has just convinced me to start learning to script in ph3. Keep up the good work~
