I don't have much of a foreword for this, let's cut to the chase:
Potential: This one is truly only limited by what people can think of. The lack of examples and ideas to start from is the only "flaw" I can think of, but it's still got the potential for long running games, despite feeling like it's designed towards stand-alone oneshots.
Mechanics: There's nothing wrong with 3d6 roll over. Add some very sweet thematic ways to handle the possible actions and their consequences, and you've got a truly above average system despite it feeling so barebones. The questionaire-style character creation adds a little more spice for first-time players, but might get old for people that replay the game.
Presentation: As with the other participants, the only thing missing would be some more detailed artwork. This one gets 5 Stars due to being the most crisp and professional looking out of all submissions.
Theme: Not much to say, as most of it has been expressed in the first two rating categories. Just clean, simple, to the point and yet stirring the braincells in a good way. The only reason I feel this doesn't quite get full score is exactly because it is so broad in what it can cover.
