Had a pretty nasty glitch happen to me. I was about 60% through Gradus when I spent my evo points to get shishishishi, and during so it went to 0%, making me lse about 150q evo points. :/
Honestly don't know what people are talking about for the difficulty. The most enemies that got through on any level for me was 2, and that was level one. Then I did flawless on every other level first try.
The best way to beat any boss is just to die to it tonnes of times until you get lucky. On Hyperion, this happened on my 4th try. On Atropos, it was the 36th try :P
I've finally found a bullet hell that is actually difficult for me, other ones don't have the 'bullet hell' feeling unless you are at a boss, this game has it all throughout the level. 5/5
