Zanac is one of those space shooter games in which you are trying to save the earth.
Due to the highly repetitive nature of this game, the hidden 9th input button (the console's Reset button) is used to enable stage select to warp to the final (12th) level. This results in an unusually long gray screen at the start of the movie. Starting on the final level with 3 lives and only the initial pea-shooter for a weapon normally makes the game near impossible to win.
This is the author's 4th iteration of this movie. It improves on the previous publication by almost 10 seconds by utilizing a hidden fairy and by better boss optimization.
