Iced surfaces make it hard for the player to start, stop and change direction. Usually, patches of ice are followed by deadly traps such as bottomless pits or spikes. Jumping negates all horizontal velocity (in most cases), which allows the player to regain a foothold. In Mega Man Powered Up, a comical slipping animation is used when the player stops moving (letting go of the D-Pad) or sharply turns a corner. Ice Man does not slip on ice.
