I'd adore a button to slow my movement down, I've played a fair bit of touhou and not being able to fine-tune my movement is driving me crazy (though I am trying to do it on Hard)
now on the second boss, I'm having the same problem on the second phase. The tear attack where he goes in the background and spawns tears around you feels particularly weird - there's no real way to know where the bullets are going to spawn, coupled with all the visual noise from his other attacks going on at the same time not getting hit feels more like luck
