8 Eyes

8 Eyes is a platforming video game for the NES. This multiplayer game requires you to explore eight different areas around earth, each one pitting you against a boss at the end of the level. At the end of each level, Orin, the main character, obtains a new sword. Most of the inspiration of the game seems to come from the classic video game Castlevania.

There is no set order on which levels you are able to play first, though each boss at the end of the level is only beatable by being hit by a certain sword.
