Hell Yeah, that is something, that is definitely something...
oh & the only part of the game that gave me an indication of wth is this difficulty was in stage 2 when the enemies shooting the red shuriken bullets starting from the very right of the stage start showing up(I think it's right before the boss shows up)...they have too much health...I couldn't kill any of them before they crowded the screen as they descended towards the bottom of the screen...other then this, no problem with difficulty(regardless of the fact that I will never 1cc either stage)...
stage 7 is somewhat the replacement of extra. but it's not meant to be the final stage. After defeating the final boss you can choose to proceed to that other unknown place where sikieiki and komachi are. they're the real culprits, after all!
and, about those kunai shooting fairies: you must memorize their positions and kill them in time. every character has a special way of doing so. I wanted to add an effect of "defeat quickly or suffer"
those fairies AFTER that, however... they're too hard. i know. i usually bomb there for the items. you can pretty much get an extra life by doing so! they're full of items
in fact this whole demo wasnt meant to be released yet

i just wanted the opinion of everyone.
i'd like you guys to report all bugs/flaws here and possibly make suggestions. no need to scream MAKE IT EASIER, 'cause i will. don't worry.
