I found this a while ago with Indie Games Roulette:
"Cuphead is a classic run 'n' gun set in the style of a fighting game universe. Inspired by cartoons of the 1930's, the visuals and audio were painstakingly created with the same techniques of the era, i.e. traditional cel animation, watercolor backgrounds and live jazz recordings. Play as Cuphead or Mugman as you traverse the islands to find new challengers, rank up, and compete in the grand tournament."
It looks amazing and awesome.
