Thanks for the edit, TTOB!
So for those who want to know more information about this game's mechanics and controls:
Circle Pad (Left or Right) - Move left or right
Circle Pad (Up) - Jump.
B Button - Light Attacks.
A Button - Heavy Attacks.
Y Button - Lock-On.
X Button - Burst.
L or R Button - Guard.
L or R Button + Circle Pad (Up or Down) - Shift planes.
During combat, your goal is to attack enemies while evading or blocking their attacks. The battlefield is separated into three planes that you can jump between to position yourself for an attack or escape an enemy. You can only attack an enemy on the same plane as your own.
By combining button presses with directions on the Circle Pad, you can perform different attacks. Some of these moves, like projectile attacks or area-of-effect moves, will consume MP points.
Pressing Y will perform a Lock-On attack that will place a target marker on the enemy if it connects. Normal attacks will then deal double the damage to the enemy, and ranged attacks will home in on it even if you're on a different plane.
Pressing X will perform Burst. This ability will drain your MP over a period of time, but will double your damage and stun nearby enemies when activated. The effects of this stack with the Lock-On attack.
Here is a
three-minute video that contains examples of the above (in Japanese, but at least you get to see them in action).
