Chack'n Pop is considered by many to be the precursor to the venerable game Bubble Bobble. The cast consists of two enemies that would later be seen in Bubble Bobble. Many fans of the Bubble Bobble series may find Chack'n Pop less fun to play due to its high degree of difficulty. The game puts the player in the role of Mr. Chack'n, who must rescue all of the hearts that were stolen during a romantic interlude between him and Miss Chack'n. Chack is an interesting character with interesting abilities. He can toss two bombs, only one in each direction at a time. He can also effortlessly go from walking on the floor to walking on the ceiling. If the ceiling is low enough, Chack can extend his legs until his head touches the ceiling to immediately begin walking on it.
