Hard Head

Although the official Title Hard Head was the same in every region, SunA's second game used to be known in Korea as "Jjanggu Baksa" (Dr. Bulgehead)3. It is incredible how many elements from other games are squeezed into a surprisingly fun melange platformer. Hard Head (and his twin in 2-player mode) carries a bubble gun that encloses enemies into bubbles, which can then be used as trampoline, just like in Bubble Bobble.
