Im stuck on the first fight with the masked boy, that is assuming theres more, HELP MEEEEE
Masked boy in the Badlands follows a very repetative battle script, he will always disappear after you string three hits with your keyblade, so stick to short combos (two hits) if you don't feel like dodging, however if you do then go ahead and chain the three hits together, but be prepared to dodge immediately after, blocking does nothing by the way.
Assuming that you are a respectable level this should not really be -too- hard, but after a while Mickey will intervene and you both will fight Masked boy, stick to the reserved battle style if you don't feel confident and let Mickey do most of the work, if you want the battle to end fast then unleash your fury on Masked boy by using a combo of magnet attacks (he has a strangely hard time dodging this) followed by a short burst of keyblade hits. Or if possible get your hands on the thunder/flame surge attacks and make multiple copies, spam them, and practically bully Masked boy to death.
If that didn't help then tell me specifically what kind of trouble you are having~
