2D platform Unity game

I made a 2D platform game in which you play the fifth element and travel trough 4 diffrent levels, based on the water, earth, air and fire elements. Because I’m an artist I made my own art for this game. This includes the backgrounds and sprites. The shapes and flow of the background have returning components, but each shape differs accordingly to the shape which I found to be fitting for that element. For instance; water and air are very flowy and peaceful, while earth and fire are pointy and dynamic. The black borders also contain little shapes that fitted the theme like; coral, plants and trees. The enemies are the elements of the game, which are shown as animated sprites.
