I don't think I've ever played a game as great as Cuphead since I started playing video games twenty years ago.
With it's run-and-gun style of gameplay, Cuphead follows the story of Cuphead and his brother Mugman as they fight bosses and collect souls for the devil in return for souls of their own. Differing from games of similar ilk, Cuphead is based more on boss fighting than level-progression; each level consists of only fighting a boss, with a few boss-less levels that serve as a way for characters to collect money.
The developers Studio MDHR really put themselves on the charts with this game. Though its name and reputation has been around since E3's 2014 conference, Cuphead lived up to the hype, and its worldwide September release garnered critical renown, scooping up multiple nominations and awards.
