Aqua people keep jumping

While on the Lesser Celestial River, you will come across aqua people that jump out of the water and attack you. If you use Escape while fighting, the aqua people will just keep jumping in and out of the water.

Turn off Battle Window

During battles with enemies, you will notice that annoying window that pops up after each attack, by you or the enemy. This can pull you out of the experience a lot. To turn this off, press Y to open the menu (when not in battle), go down to "System" and the second BTL selection. Choose "Popup" to make it so only the damage numbers will appear above the enemies heads, like Final Fantasy.
