The rules:
1. The size is not limited, but please don't make it TOO large, cause most people won't play levels with a size of a football field (and you get less points)
2. NO GLITCHES except as a pure decoration. (If you want glitches, you may make an another competition idea of a most glitchy level.

3. No hex-editing, cause it will be unstable on a lot of systems.
4. That's all.
About other things (like scoring, etc...) I'm uncertain...
