Ever seen a dragon eat soap? Neither have I, but the effect seems to be visible in Bubble Bobble. Two cute dragons, one of which you can control (or both in two player mode) blow colorful bubbles at equally colorful enemies. Most of the time these enemies resemble random doodlings. Your object is to capture them inside bubbles and then pop them. When you burst a bubble with an enemy trapped inside, it turns into a piece of fruit that you can eat for extra points. The goal of each level is to bubble all enemies and pop them.
Gameplay is self-explanatory. Let your three-year-old nephew try this game, and he'll be able to play it within five minutes, only having trouble understanding that he should capture the enemy in a bubble first, then jump at it. You just use the arrow keys and the Alt key, although you can always remap the keys to suit your needs. Nothing fancy, nothing complicated. It's just like those one-buttoned joysticks from back in the days.
As for the story... well, to be frank, does it need one? Beat this game and there'll be a certain someone who won't have left his computer for days. This game is just a fun way to pass some time, trying to get as many points as you can while enjoying the fun, colorful look of the game and the cuteness of the characters. Any attempt at a story would only make the game less fun, as it would get in the way of playing. Bubble Bobble is perfect for killing half an hour of lunchbreak and being carefree for that time.
