Okay, I'll give you the save folder.
Save 6 - She can go everywhere (finished all stage except the final stage, can enter the CG room)
Save 7 - Before the final boss
You must set normal mode, because that's the mode that helps you by refilling +7 HP when you are almost die (I think... 5HP remaining). Honestly, no item could do like that during on the battle, pal.
But.. honestly, this game is easier than Touhou game series pal.
Meet this black guys in the morning time, he'll give you the meat after a H scene.
"What a horrible night on having a curse" (Castlevania) :]]]]]]]]
If you enter the red door on the horrible night, you'll see what happen next.... (OMG... creepy....)
"The morning sun has vanquished the horrible night" (Castlevania) :]]]]]]]
You can go without any troubles and.... prepare to fight the creepy white girl
UPDATE: Oops, almost forget.... To go to the CG room, click the pink item with "ERO" => 100 % CG (finish the game first)
Besides, after finishing the game, no new game + or more adventures
Whatever, pretty funny.... danmaku-type in RPG game with pretty nice music (specially Merry Christmas :]]]]])
