Previously released on PlayStation Vita, King Oddball for PlayStation 4 is also available now in North America, 10tons Ltd. announced. The goal of King Oddball is to clear the screen of enemies with three rocks or less. The King swings a rock back and forth by his amazingly stretchy tongue, and the player releases the rock by pressing a button. The trick is to crush several enemies with each rock by anticipating how the rock will bounce and tumble after release. Starting off as casually mellow, the level of challenge steadily rises to excruciating heights.
