Been away a long time but i recently found out about the new release spoiler and for the timespan of finishing it im back hyped about touhou.
I wanted to know how i can unlock the spoiler level in double spoiler, is it really AFTER unlocking ex?
If so damn hard to get that second char 
some info would be nice- john
Actually, compared to the task of unlocking and clearing EX spellcards in Shoot the Bullet, unlocking Hatate is actually really easy.
Each scene only requires you to clear a couple of the spellcards from the previous set, and there's usually enough that are fairly easy once you understand what's going on. I barely managed to unlock level 10 in StB, nevermind level EX; but I was very able to unlock Hatate in DS.
