What is the aim of this contest? Is it to make the hardest level or to make the most creative level or what?

Are we allowed to change any sprites or of the programming? And can we add any enemies?

Edit: This could easily be made fully into code.
Edit2: When is the deadline?

kind of both, i'm thinking about making a player edition of impossible game and putting the winners levels on the game.
edit:the dead line is when ever we get all the levels we need
edit:ya u an add sprites for your enemies but besides tht no ,i guess you can add your own music and back ground to it but thats it
