The game was released in Japan on February 10, 1989, in the U.S. on March 1990, in Europe on November 30, 1990 (information from Wikipedia). Didn't include every Gorilla boss fight because would make the video longer, but at least I included the ending. Footages by NintendoComplete and World Of Longplays
