Forward Air launches at more variable angles.
Down Air has stronger base knockback.
Nohr Side Special works similarly to how it does in Smash. With a forwards and backwards kick, but now only grounded opponents can be pinned.
Hoshido Up Special has a strong sweetspot at the tip.
Overhauled Hoshido Ultra's visuals. Now it does more damage and knockback at the tip.
Added smears to Jab, Forward Tilt, Down Tilt, Up Strong, Down Strong, FAir, and UAir.
Added LAP support.

Corrin chooses to Smack. Somehow less weird sounding than choosing to Smash.
