it’s perfectly fine to have functions like pause, level select and such. The purpose of the jam is to see who can be the most creative with game play limited to one button. If you want to have a typical card game where you can use a mouse with drop down menus and such that is within the rules. But, personally I dont see that as creative and may not vote favorably towards it. However, this is voted on by the other people Jam so maybe they will see it differently.
