Ok, while taking a short break from homework, I played TFU for my PSP. And I do an aerial combo. Now, aerial combos in this version, and I assume the PS2 and Wii versions also, it's always Jump, slash, slash, saber ground quake thing, or jumping-uppercut, slash, slash, saber ground quake.
Now, I was randomly pressing the buttons in the air, and I did Jump, slash, slash, backflip kick/with some white colored, ground quake effect thing on under my character while doing the backflip kick. After I did that, I was trying over and over again to try and do it again but no luck at all.
Now, I don't know if maybe I just blinked and didn't see it well, but I'm 90% sure I saw a backflip of some kind that sent the enemy flying from my attack.
"All too easy."
