You are now able to stall while jumping, effectively freezing yourself in place at any point. It lasts a good second.
During this time, you are able to perform any aerial attack, as well as air guard. You can also press any direction
and the mech will shimmy over there for about a third-screen's length, then stall a second time when he stops.
During this second stall, and even during the Stall Dash leading up to it, you may still perform any air attack and even guard.
Also, you can cancel any of these aerial attacks you throw out by pressing Down (which cancels the Stall and drops you down toward the ground)
Pressing Down/Back or Down/Forward will steer you into that direction as you fall.
On your final Air Stall, you can't perform dashes out of it, but you can cancel it by pressing Down.
