Come on, don't be such a pessimist. It doesn't necessarily mean your level is bad, you know. Just that you shouldn't assume a level is good even though you spent a lot of time on it. It goes for everyone, not just you.

It has been stated before that basis of judging in this contest is focused on design. Just because a bad from a design standpoint doesn't necessarily mean it's completely bad (though I do consider level design to be of high importance). Not everyone considers competent design to be the main focus of their hacks, and to them, good levels focus on other aspects like graphics and gimmicks. They probably wouldn't score well in this particular contest, but that's because their definition of a good level is subjective.
