Bubble Bobble Evolution is not just a 3D update of the classic platformer - it is much more than that; a completely new game in itself, hence the title. The most obvious new feature is the level structure. Gone is the classic static structure of Bubble Bobble and in its place are three screens on a central spindle, which the player can move between whenever they want. There are also new bubble types and added puzzle elements to the game.
The Story Mode re-tells the classic story of two human brothers trapped in bubble-blowing dinosaur bodies by an evil nemesis. There is a slight difference to the original Bubble Bobble - the gameplay actually takes place in two Towers of Entertainment instead of one.
The all-new puzzle elements to Bubble Bobble Evolution really do add an extra dimension to the game. Using gaming tactics that are familiar in all Bubble Bobble titles, players must now solve a different puzzle during each level. These can range from watering a seed so it can grow to fill a gap, to finding a source of fire to melt a barrier made of ice. Everything needed to solve these puzzles is available on the three screens that make up the level.
So you see, Bubble Bobble has evolved especially for your PSP.
