Overview
This game is a pirate version of "Bubble bobble". Unlike the original game:
The left player ('Bub') can have only a total of two extends.
The monsters 'Mighta', 'Hidegonsu', and 'Drunk' do not throw their projectile weapons (i.e. 'Mighta' does not throw his slow-moving stone balls, 'Hidegonsu' does not throw his fast-moving fireballs, and 'Drunk' does not throw his boomerang bottles). However, the 'Invader' monster, who appears in 'Normal' mode only, does throw his laser projectile.
