In this second DS Bubble Bobble game, classic Bubble Bobble level designs are now spread across the two DS screens, with the new challenge of having players switch characters during play to take out certain color-coded enemies. Bub, Bob and newcomer Bubu each shoot bubbles in different hues, and can be switched in the blink of an eye with a tap of a shoulder button. A new star bubble has also been introduced which allows the player to change the colour of all enemies when burst, with an ability to choose the enemies' colour by shooting the star bubble with the player's selected character. Also new to the Bubble Bobble template is an entirely new method of obtaining a chance to continue once all lives are lost, with several touchscreen-based micro games offering you the chance to continue on. Moving beyond the 100-level single player mode, Bubble Bobble Double Shot's multiplayer expands on the multi-character model by offering co-operative play for up to three players.
