Floor kick

A floor kick, like a wall kick, happens when a player rotates a piece when no space exists in the squares where that tetromino would normally occupy after the rotation when rotating against the floor opposed to the wall. To compensate, the game sets a certain number of alternative spaces for the tetromino to look. Floor kicks first appeared in later TGM games because 20G made some tetrominoes difficult to manage. I and T must have a floor kick to rotate here.
