KH birth by sleep questions

alright well this is really annoying but...
is each character like a difficulty?
Ventus story is kind of easy
Aqua's story is somewhat like normal
Terra's story is somewhat impossible or just hard.

come now tell me if i am right or is this just a flaw and i am not very good >_>

no it depends on your settings you choose for the beginning of the game.
but overall if you choose beginner it should be somewhat easy epending on how well you followed instrutions in the beginning of the game.

lol how do you beat the mirror thing it always gets me with those attacks of it and i always counter any other suggest on how do beat um?

you have to deflect then role and attack.

oh ok i understand now.

I have a little question...
if i have a 1GB for my PSP and the game asks me to use up 620MB would that take a lot of space...?
i just need to know how much space am i giving up cause i have some other games,music and downloads on it also...

the game then is taking up about 65% of the memory now if im right u should have about............380MB left after all that this is more of a tech question anymore let me know im majoring in it so i could help with a few things
