Ghosts 'n Goblins

It says here on your resume you beat Ghost 'n Goblins? We might as well switch seats now you handsome strong man.

Ghosts n' Goblins is basically the harder, darker cousin of Super Mario Bros. And when I say harder I mean it's absolutely brutal. - Full Review

Would absolutely be willing to call this the hardest game ever made. I would have a better chance becoming an Olympic Athlete than ever finishing this.

This was the first game I played on my new Retroid Pocket 6 and what a perfect selection it was! First of all, GnG absolutely earns its reputation as the hardest NES game - this is a monster! If not for save states, this would've taken me weeks. Even still, it's nightmarishly difficult but rather fair, especially with unlimited continues. The randomness of the enemies is brutal, the graphics are dated and the gameplay is a bit stilted but this is gold from the early NES.

It may be an appealing game, but it is by no means a kind one.

This is too hard for me... I'm not strong enough :(
