How to do animation and design for any 2D game?

Hi,

I am going through Unity 3D tutorials for past 20 days.They are simply awesome, thumbs up to developer.I want to develop a game similar to Mario but I don’t know the animation part.How to build character like Mario, the background, sprite texture etc.I am quite comfortable with scripting but I really don’t know how to proceed with animation and design part.I need help and valuable suggestion from the forum.Thank You.

You would use a program like Photoshop to draw 2D images.

There are many similar programs available, if you do not like Photoshop.
