Bubble Bobble Part 2 brought many changes to the series. The characters were much larger than in most of the other games.
You also had the ability to charge up bubbles, and if you held them long enough, you could fly.
The gameplay was pretty basic Bubble Bobble stuff, but it was still fun.
Right now, I have no downloads available for BB2, but soon I'll have box art, and possibly a movie of the intro.
