It's all that stupid cats fault. I can just about get through the entire first 4 stages without loosing a single life (1 or 2 at most, usually on Satori), but stages 5 and 6 will take every single one of my extra lives and thats before I even get to that stupid radioactive birdbrain.
it happened to me too when I was still trying to 1cc normal mode...
Enter Orin with 9 lives, came out with 4, then just proceed to blow all of them away at Okuu for some reason.
Can't believe how much I raged.
The only way I see is to practice stage 5 to death...
like memorize the stage (spawn points of orbs, where not to shoot, gap abuse, planned bombs, etc)
and like fight orin to death (50+ times or something), with many planned bomb if necessary.
But Okuu...That final spell card is just evil. Bullets coming from both sides AND you being drawn into the center.
Get into a fixed tapping pattern (like right/left, down x3, repeat) when on that card so that you only have to focus on dodging the small dots from above.
Apparently the difficult of that card doesn't increase very much from normal to lunatic,
and I think that's why everybody is saying it's loleasy when it might hard for others.
