Mr Sunglasses NES Action! 8 Eyes
8 Eyes is a 2D action platforming video game developed by Thinking Rabbit for the NES . The game features eight levels, and can be played by one or two players. The gameplay and graphical style are noticeably similar to Castlevania with some Megaman Flavor.
Overall it is a fun game, but pretty tough. It never felt to unfair however so with some practice you can really see an improvement to your playing, much like modern favorites such as Dark souls.
