Personally, I liked the passive water run ability. I want that back and not limited to super forms.
Then you should have it suggested as a Secondary ability.
As a matter of fact, I have a few secondary abilitys.
Shield
(Spin/Secondary Ability)
By holding down the Spindash Button, You can use a shield that will block all incoming attacks from in front of you. You can also walk around slowly when doing this. This is based on the Shield Bot, or Protoman and Sniper Joe from the Megaman series. One frame is for pulling out the shield, or putting it away. Another frame is for standing, and the last two frames are for walking. This includes the standing frame in the middle of the walking animation. This removes the spinjump, as the ability uses the spin frames. You also can't shoot rings when using this ability. Also, enemies are not damaged when this is used, as they bounce off if they hit the front of you.
Slide
(Spin/Secondary Ability)
By holding down the Spin Button, you can slide on the ground in front of you. This is based on megaman's Slide ability from Megaman 3 and onwards. Two frames are used for going into the animation or coming out of it, and the other two frames are used for sliding. This removes the spinjump, as the ability uses the spin frames. Also, enemys are not damaged when this is used. Instead, you take damage as you would normally.
Light Step
(Spin/Secondary Ability)
If you run off a ledge, you hover until you are moving at under half of your running speed afterwards, you fall to the ground. Please note that you slow down when you run off a ledge until you fall. You can jump during this period, to jump further then you may normally. Also, you can run on water. This is based on the Hover Boots from The Legend of Zelda: Ocarnia of Time.
Dash Punch
(Spin/Secondary Ability)
Press the spin button while moving to dash at your current speed for one second. You can hover over the ground while dashing. If you press the spin button when standing still, you just punch what is in front of you. This removes the spinjump, as the ability uses the spin frames. The first two frames are for starting or ending the dash/punch and the other two are for dashing/punching. This is based on Bowser's move from Mario and Luigi: Bowser's Inside Story.
