Rainbow Islands: The Story of Bubble Bobble II

Plot: 'Following the events of Bubble Bobble, Bubby and Bobby set out to defeat the "Dark Shadow" and rescue the Rainbow Islands. The Dark Shadow is the entity responsible for the events in Bubble Bobble.'

This longplay aims for the best ending in the game. To get that, the 7 big diamonds and 3 mirrors must be collected. I also included a second playthrough at 1:01:58 where I show all the secret rooms, which requires all small diamonds to be collected in order.
