Dude, a couple hours ago I tested your 0.5 version, one I've heard so much about =P
It was definitely interesting: that U-Smash looks completely sick especially =D The F-Smash looks amazing too.
For the F-Smash tho, if you want, you can use trajectory 365: it has hitstun, but no knockback, so you can pack on the combos.
And yeah, that Side-B is soo broken XD
