This level is quite ugly.

The sky needs to be fixed and no level should be flat. Levels should have all sorts of different types of land. It should also have a wall around the level. It makes it look better. It also needs music and maybe even a few more text signs saying who it's by. Oh and you should change the name because I said that you should have all sorts of different types of land, and that would mean it is no longer a flat battle. Try to think of a more original name. Try put this stuff into your level.
