I'll try the script, hope to get a good replay.
First things first, your nonspells. I hate arrows. They have bad hitboxes, both in TD and in Danmakufu. I'm not too sure how to explain why, but something tells me they are as deceptive as Sakuya's knives.
Second: Your first spell. With this type of spellcard, I thought maybe the moons would actually curve in towards you. Thank goodness it didn't do that. Maybe you should put an indicator as to where your moon bullets would go. Also, arrow danmaku again. Very good job otherwise.
Your second nonspell. I don't like it - Eirin keeps running away (and it isn't helping that I'm using ReimuB...)
Pretty good second spellcard, actually. Nothing to say about this.
Third nonspell: Eirin's running away just becomes a nuisance, and it's pretty much impossible to move between the rows of arrows. I don't like this one.
Third spell: This is a bad card. Deceptive hitboxes + seemingly turning (?) bullets = disaster.
Fourth spell: Eh... I can probably see what you're doing here, but having a Keine + Utsuho card might not work as a final card. Also, bad hitboxes.
Quick note: Your backgrounds like to match with the color of the bullets. This means I can't see what's a bullet and what's part of the background. That should be fixed.
Now creating replay.
