The gameplay of the original Bubble Bobble game is brought to life on the PSP. Because they have been kidnapped and are held captive in two towers filled with puzzles, Bub and Bob must work together to solve them while learning new strategies to free themselves.
You may now blow rectangular bubbles in addition to the more common yoyo bubbles. The recognizable soundtrack from Bubble Bobble has been brought back, but this time it features bass and other fascinating effects.
