I firmly believe Reimu A to be the superior choice in EoSD, if only for the stages. The homing makes them so much easier.
ReimuA is by far the worst choice for EoSD stages. The stages in EoSD are all very easy once you learn them, even on Lunatic. They are nearly completely trivial, in fact. However, this is only if you can do enough damage to kill the tougher fairies quickly. ReimuA cannot do this, and she suffers from it at the following points:
- Second half of stage three. Still trivializable for ReimuA, but every other character type has a lot more room for error.
- The three fairies immediately before Patchy in stage four. These are essentially impossible for ReimuA without extreme luck or a bomb, but fairly easy for everyone else as long as you use the proper method.
- The "wall" fairies before midboss Sakuya in stage five. ReimuA requires a combination of luck and very quick reading and reaction here. The other shot types trivialize it.
This doesn't sound like a lot, but keep in mind that the second and third points basically require bombing and that Reimu's homing really does very little for her. Unlike, say, IN, EoSD doesn't have weak enemies flying around everywhere covering the screen with death bullets. Instead it relies primarily on forcing the player to stream. A lot. And if you don't learn how to properly stream the stages then you will die regardless of who you are using (see stage four Lunatic). The only time on the stage where ReimuA has a significant advantage is the beginning of stage six on Lunatic, as she kills the enemies on both sides of the screen resulting on much fewer bullets everywhere. But this isn't enough to make up for the difficulties she faces in other places, especially since this section isn't all that hard for the other shot types anyway.
ReimuA shines because she has a very powerful bomb, is well equipped to deal with bosses that move very randomly, and has a relatively easy Patchy battle.
Attempting Rings of Death timeout
Expect me to do more attempts at timeout. Maybe I'll put a video up instead.
I tried that for a while. I think I got it down to two or three deaths and no bombs. I'd suggest trying it with Alice, as her bomb is so weak that it barely does anything to Mokou's lifebar (Reimu's bomb, especially her deathbomb, can be very problematic here if you don't want the attack to end). The difference in hitbox size doesn't really matter, as the gaps are big, just traveling very fast.
