Ok, updated.
For now, I'm gonna just go review the bosses.
Stage 4:
NS01: Ok. Maybe you should make the bullets waver in a sine wave instead of switching from one side to another. Just a "looks more beautiful" thing.
NS02: Hey there, Chen. Too glaringly obvious a reference.
SP01: Umm... ok?
NS03: This is what I like to see. Good.
SP02: A bit awkward movement there. Fairies might have to move slower.
SP03: Good. A bit random, but that's not too bad.
SP04: Too Keine-like. Good otherwise.
Stage 5:
NS01:

NS02: Much easier. Thank god.
SP02: Danmaku Centrifuge. Enough said. Ok, though.
NS03: I swear, I'm not going to rush up to near Emi and dodge from there. Instead I'm gonna squeeze through the gaps in between the orange bullets.
SP03: Reminds me of Pokemon. Really cool.
SP04: I officially render
Luminous Dream impossible to try no-vertical runs with. Good spellcard, though.
Stage 6:
NS01: Good.
SP01: I'm curious as to why you removed bomb resistance from the lasers...
NS02: Very very bad! I can't keep up with the bullets going slow and fast and slow and fast. It's always random where they stop as well. It's literally too dense to move between the bullets when they're slow, too.
SP02: Demon Binding Ring.
NS03: Mima used Tackle! It's a critical hit. Marisa fainted.
SP03: Eh... Ok.
NS04: A lot of spellcards are referenced in this. Nondirectional, Delusion Butterfly, etc. Ok, though.
SP04: This is actually really brilliant.
SP05: Hah, everything but the player is greyscaled.
Attached is a way to cheese the first part of the last spell card of the main game, ending with a purposeful (?) ram into a familiar (which strangely has a hitbox). Perhaps you should do something to prevent people from doing that? [attach=1]
