Well Tatsuma I played your RPG with 2 friends. I was Cloud, the first was with Master Chief and the other with Kirby. Master Chief killed Ganon (Final boss) only with his specialization <-Spelled wrong i know
I speak about the one that deals 4000k demage Shadow Strike on Impact. I think this is a bug
Btw When I had Blizzard Materia, Materia Blade, Ultima weapon and the other Materia I forgot whitch -_-' I was unable to create Ultimate Sword. I speak about the sword where is in the hous near the Graveyard. Blizzard Materia is undroppable item!
Another thing: Training Area bugs everytime I dont know why. I buy a battle against Gato, win and no training evermore, or buy other training the ones with time and I'm unable to buy other trainings. If Cloud use ''Omnislash'' and then die he is revived, but also he is teleported to the spot where I casted Omnislash (A free port iei)
