Alright, I'll refrain from commenting on anything that hasn't been noticeably changed from the last time I saw it.
2nd Spell: Ok, I like the added knives, there was a lot more to dodge through this time. However, although there were more bubbles, they still didn't feel like a threat. What Sakuya does in EoSD is force you to dodge the bubbles and the knives at the same time right after the timestop. I think ZUN does this by lowering the speed of the bubbles right after the timestop, but I'm not sure. What you could do here is fire the bubbles a little later than they are now, or simply fire the knives sooner. Note that this change isn't that necessary, the spell is fine, I just find it a bit easy to do. But that is totally fine, they can't all be super hard. It's entirely up to you.
3rd Spell: Oh you didn't..... Of course you just had to add more Yumeko knives, DIDN'T YOU The changes are fine, I was happy with it before, too. Just note that adding the additional yellow knife wave takes away dodging the aimed knives, unless of course you were to make the spell longer but that's up to you.
4th Nonspell: Ok, I like this pattern, though it is very scary the first time you see it. Looks can be deceiving however, and is rather simple upon further inspection. However, it is still difficult, more so than the previous nonspells. Good job.
5th Nonspell: Great. Just great, all of Sakuya's annoying nonspells in one convenient place. I don't really have too much to say here other than nice recreation/combination of Sakuya's nonspells from EoSD. It felt a little easier than the last, but that's probably just me being intimidated by the last one, while this is one that looks familiar.
Curious as to why there were no spellcards added, but everyone works on their projects a little differently I suppose. Nice work, I look forward to more in the future.
P.S. Almost forgot to mention that you left the Alice script description in the Shinki-Sakuya stage description, but you would have probably noticed that eventually.
P.P.S. Also forgot to mention the that you might want to make the bubbles in "Chain of Creation" bomb resistant, as dying or bombing at a particular time removes all bullets from the screen.
