Hi there epicandy13. Believe it or not, I designed Beat (the name of the character) before I found out about Meat boy. And the only similarities with Meat Boy are the shape (square) and color (red), both of which can't be copyrighted.
Beat's main theme is how he moves to the beat of music (hence the headphones that he is wearing). There is no intention to copy Meat boy nor was there any need to.
Hope that clears things up.
