To be fair, that boss does seem like it'd be pretty difficult to fight for the first time. I'm only lucky I managed to beat him by accident.
Yeah right, difficult my- the battle is just confusing and slow, so it ends up getting boring, since it is use the boost to get closer to the Time Eater without it defending itself seriously, The battle against Perfect Chaos was a spectacle and the Egg-Dragoon constantly attacks you forcing you to move around, be aware of what the enemy is doing because he attacks you erratically from all angles and even plays with perspective and pace, damn, even the Time Eater in the 3DS version was much better because it actually try it.
