QuoteInterpretation - How creatively you interpreted the gimmick name; more interesting or unique ideas get more points (40 points) (This is the main idea, if you don't have it, you are disqualified!)
Execution - How well your gimmick was made; was it buggy? Was it fun? Was it made badly to where it was annoying to work with? Also, how well does it work with the level itself? (20 points)
Theme - How well your level fits the vague gimmick (10 points)
Level Design - How well the level was built, how fun it was to play, etc. (This includes grammars as well!) (20 points)
Visuals - How well the palettes look, how well the GFX you used looks and fits with your level theme, etc (5 points)
Difficulty - Was it the good kind of difficulty, or was it annoyingly artificial? (5 points)
That's basically how this will be judged. The better you do following and expressing your level through those catagories, the higher your total score will be.
