Name: Double Spin Jump
Author & Submitted By: MaxodeX
When Mario is in the air, this generator allows him to press the A button for an extra Spin-Jump. My first sprite to be made and submitted!
Sprites that Mario can stand on, such as keys, Mega Moles, and message blocks, do not set the 'Mario is on ground' flag, and thus the generator considers him still in the air. Once Mario has "consumed" his extra spin jump while on one of these sprites, either while jumping and spin jumping in the air or just directly spin jumping while standing on it, he cannot spin jump again until he touches the ground.
Also, I recommend you mention in the description that this causes two minor gameplay changes: it is possible for Mario to spin-jump while holding an item if he is in the air, and that he can no longer jump off of Yoshi without spin-jumping.
Edit: Fixed title.
