Well, the background twist code was something I "borrowed" [Is expecting another message from Helepolis regarding another plagiarism issue for the twist] from PhantomSong and the background image itself was a modification from EoSD Stage 6's image. I was mostly aiming to "reproduce" Makai.
I can't animate Byakuren (properly) because of the big circles. (And yes, it was the first and apparently only Touhou 12 Byakuren spritesheet I found)
Nonspells ARE supposed to overlap each other. Without the slow bullets, there would be no challenge at all on her nonspells. Also, because it's not random and instead static, I had to make her to move.
Well, the mist (purple danmaku / bullets) was supposed to be odd, actually. Though it's just static + angular velocity spirals and thus it's not really hard - just that it may kill you with the large purple danmaku. Said large purple danmaku is random, so...
The focus effect (and the explosion effect to when Byakuren dies) is from Ran Yakumo's Effects library. It's pretty flexible, easy to understand, and gives gorgeous results. His thread is called "Ran's Magical Workbench", if you're interested on his Effects library. I'll always give credit because it's really good.
Sutra of Lotus's 1st wave's purpose was to overlap the 2nd wave and reduce your space to nothing when dodging the last and few bullets. :V
Fourth spell was actually done in a rush, since I had nothing to do. Though, I used the same butterfly flower pattern in the second spell.
"Danmaku is always a visual thing" (words of PhantomSong), that's the reason the amulets have spell resistance. After all, even though they're the "body" of the pattern, they're not really dangerous, just walling. :V
I also like rainbows, and using angular velocity and flower-shaped patterns is my pride and joy (Heh). So I combined all those three and that's what I got. Because it was sort of similar to Byakuren's last spell in UFO, I named it "Undefined Fantastic Object". The reason is simple:
"Looks like a rainbow-colored flower at first, but then it becomes something else. Something unknown, and really fantastic. An undefined fantastic object."
