Probably. "Cuphead" is supposed to be a throwback to the classic cartoon shorts made by Fleischer Studios in the 1930's, and they would often feature cartoons that had a "Bouncing Ball" with them. In fact, a "Bouncing Ball" cartoon made by Fleischer, was actually the very first cartoon to be a SOUND cartoon, in 1927; although it wasn't synchronized the way that Disney's "Steamboat Willie" was. Anyways, just thought you might like to know that "Cuphead" is supposed to be a real-life Fleischer cartoon that you can play as a video game. Enough said!
