>>61050679up is the thumb button at the bottom for these layouts, which is standard. seems weird but its not really for 2d fighters.
if you imagine an airdash it would be a simple double tap of up, up + left/right
and 360 motion for command grabs would be a piano roll motion of left, down, right, right + up + attack button.
that would actually be harder to do if it was like say, a WASD layout. players that use keyboard for fighting games often have spacebar as up for example.
