How can I make a character defy gravity by holding on screen.

Hello everyone.

I want to make a game in which my character floats up towards the top of the screen essentially defying gravity. I am able to have the character float away, but I do not know how to make the character come back down when the screen is held.

Thanks for any help.

@TreySmith Is there a way to make the character come back to the bottom by holding a button. I currently have the Char Move Down button on the game field but it does not affect the character.
