Here goes:
Nonspell 1
FINALLY! Someone remembers that Extra nonspells are easy! The bullets are barely visible, but there aren't many of them, so that's fine.
High-Powered Telescope "Cloverleaf Quasar"
'High-Powered Telescope' is seriously only two kanji? Huh. Never would'a thunk it. Anyway, it's too long and laggy to really tell you the difficulty, but seeing as it's fine when the framerate is dancing around forty, the bullets are probably too fast. Try less frequent waves first, though. Ah, derp, got hit, counterbomb --
wut
...yeah, you'll want to one of these code snippets. Or both.
//Place in MainLoop
if(!OnBomb) {
SetCollisionA(32,0);
SetCollisionB(16,0);
}
//Place in Initialize
SetDamageRate(20,0);
Heck, try the last one anyway, and divide the HP by five. It'll be just as long and you'll get that thing where the spell card health bar is about, well, a fifth of the nonspell health bar.
Nonspell 2:
It would be fine if you could see the bullets. I tried it with a custom player with alpha shots and it was fine, so... Stick with alpha bullets, 'k?
Star-Crossed "Binary Swing"
YES
Easy and fun, exactly as nonspell 2 is supposed to be. It's about as hard as Yukari's Balance of Motion and Stillness; i.e., capturing is to be expected.
Nonspell 3
NO SERIOUSLY STOP WITH THE ADDITIVE BULLETS. Still perfect difficulty-level otherwise.
Galaxy Sign "Center of the Universe"
Hey! I remember back when this was called "Long-Arm and Long-Leg." Oh, those were the days...
It's kind of easy, but I wouldn't change it if I were you. It's a gimmicky thing; balancing now would probably make it way too hard.
Nonspell 4
...didn't see that coming.
It's not too hard, though. Don't change if you don't want to. It's kind of out of nowhere, though.
Black Void "Insatiable, Inescapable Dark"
It looks like it should be gimmicky, but oddly enough, it isn't. :/ It runs at about 30 FPS on my comp, so while it's probably okay difficulty-wise, I can't say for sure.
Nonspell 5
Another good one, if you can see the bullets. It's more trying than the other two, with more angles to play with. Still pseudo-random stuff everywhere.
Heavenly "Five Solas"
Okay, back to the bottom of the screen to set up for -- FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
Delay much?! Anyway, it's a really cool idea, but I feel like you have too much going on. The colours clash horribly. From a gameplay perspective, it's fine; from a design perspective, the additive green and the alpha red/orange/yellow are awful together. I'd see if I could unify the colours more while they're going to share the screen -- maybe white bouncy things instead of green ones?
Nonspell 6
This looks familiar. >>
It hasn't changed a bit -- it's like the difference between Ran and Yukari's first three nonspells, where the difference doesn't actually change the dodging strategy. Except it also seems to be much easier and Extra-ey than NS 4. Hmm.
Astrology Sign "Starry Scattergraph"
YEAAAAAAAAAAAAAHHHHH
This one is awesome. Keep it.
Cosmic Sign "Supernova Bloom"
What, that's it? :/
Anyway, what I'd do is graduate each colour of bullet (e.g. the blue sideways ones, the yellow slow ones, the red tiny ones) as time and/or boss health wears on. It's very short as is for what I presume is meant to be a final Spell Card.
It's rather easy for an Extra Stage, but balancing is going to be a nightmare. :/ Oh, well.
