I got bored so I timed out some Ten Desires spellcards in 90fps. No Overdrives. I didn't use Reimu for any of them in order to increase the challenge a bit, cheating hitbox and all, though I am using Reimu for some of the harder cards that I haven't timed out yet since they're pretty ridiculous. Anyway...
Saigyou Cherry Blossom Blizzard (no focus), but no other Yuyuko cards were timed out since they're too boring.
Two of Kyoukous boss cards were timed out but they are too easy to really care about.
Poison Murder, Guhun Yegui, Tongling Yoshika, Dao Fetal Movement (too easy so didn't save replay), Mononobe's Eighty Sake Cups and Sakuraiji in Flames were timed out and some of them were quite hard and all of them (except for DFM) were fun.
I've had many attempts at Iwafune Ascending to Heaven, Oomonoimi's Dinner (getting to the amulet spam phase ASAP), Prince Shoutoku's Out-of-place Artifact and Honour the Avoidance of Defiance, all with Reimu, but no luck yet. I also found out that Newborn Divine Spirit has a timeout phase, and I didn't quite have time to grasp it before I died so I think I'm skipping it because I don't like it.
This game has some neat spells and although some of them are far too easy, playing in 90fps fixes that!
