Beat'em Art - Fully Completed

The Gameplay is very simple : Just slice your enemies and watch your health bar(on the right)! This is my first experience in game development. I enjoyed this competition so much. And I am happy, that I take a part in this big competition.
Please leave comments with advices. I really appreciate your help.
