things that I'd like to know..
- maybe chaining for the gray spirits require timing on enemy destruction, rather than speedkilling (noticeable on the first wave of the first stage, where you get gray spirits even if you kill them asap, considering the time the latter fairies take to appear)
- maybe overlapping options on bosses is what makes more spirits to appear from them? (together with shooting them for a while) Or maybe it's just shooting them for a while, or maybe it's pointblanking them for a while (also, if you're ever forced to stop pointblanking, how long does it take for said pointblank chain to end?)
- spirit gain while pointblanking bosses or enemies, is it affected by damage dealt or by amount of shots fired? (characters with high firerate or those who fire more shots per wave could gain spirit faster, or even Youmu's unfocused shots could gain the same amount, allowing her to milk bosses a little more than other characters?)
maybe the game needs familiars for more milking :p (IN had them, at times).. maybe (once again this word

) runs on the full version may sacrifice spellcard bonuses for spirit gain, and then have some hypers against later nonspells but the players purposedly stop firing when the nonspell is about to be shot down, to avoid entering spellcards with hypers? (there may be some stages/places which rewards players for timing the destruction of enemies to make them yield spirits, which linger on the screen, and then, when they're nearly disappearing, the player uses hyper and gets more spirits than he/she would if he/she just collected the spirits before activating hyper..)
