Ok in my opinion the Cuphead show is a work in progress and maybe if the creators of the show see this and change the plot then I'll give this a 5 out of 5 stars
What they should do is 1st have the devil and the king of dice be a sort of character that appears in storytelling or something like that and have Cuphead and mugman go around ink island meeting all the bosses and side characters for the 1st season and maybe every few episodes just have them do something else then in the 2nd season have them deal with the devil and fight the bosses ect ect
