A mock hover mode if you hold K. During this hover mode,
you can freely move around by using the directional buttons. Releasing K at any time
will result in her flying forward and headbutting the enemy, knocking them away.
You can airdash cancel this hover mode (simply double-tapping backwards or forwards).
She has this cool extra feature where if you press any K during the flying headbutt portion
before it has connected, she will teleport back on the screen and come flying forward again! However this costs 250 power.
The EX version loses both the hover move and teleporting features, but it gains projectile invulnerability.
