NES Sky Serpents

Possibly in the game, the player controls the Young Norse Warrior and has to run and avoid Sky Serpents. The game has over 4 levels. It is more likely than not that this is a prequel to sky serpents, as in the end of the initial game most all of the sky serpents have been killed off.

Controls
Although none have been announced, it is assumed the character automatically moves forward and the player must use the arrow keys to move along the grid-like ground, the player must also use weapons of some sort to kill the sky serpents
