Like UNDERTALE, this game soars in difficulty level. there have been many times where i found my self raging by flipping my switch over, but its just so satisfying once the boss or level is completed.
CupHead Don't Deal With The Devil has you do the opposite of the title. THERE WILL BE SPOILERS. SO IF YOU DON'T LIKE THAT, TURN BACK NOW.
Cuphead (full title: Cuphead: Don't Deal with the Devil) is a run and gun indie video game developed and published by StudioMDHR. First announced in 2013, the game was released for Microsoft Windows and Xbox One in September 29, 2017, for macOS in October 19, 2018, and for Nintendo Switch in April 18, 2019. The game was inspired by the rubber hose style of animation used in cartoons of the 1930s, such as the work of studios Fleischer and Walt Disney Animation, and seeks to emulate their subversive and surrealist qualities.
Cuphead features one or two players taking control of animated characters Cuphead and his brother Mugman to fight through several levels that culminate in boss fights as to repay their debt to The Devil. The game was praised for its art style and noted for its challenging difficulty. It was both a critical and commercial success, winning several awards and selling over four million copies by July 2019. An animated series based on the game, entitled The Cuphead Show!, is in production by Netflix.
