These aren't really rate-able as games, since what does it mean to call a movement-mechanic test "Really not very good at all" or "Amazing?" Since it's worthless as a game, a single star is fair as such, but what if as a movement-mechanic it is indeed amazing?
Right now the arcade is cluttered with non-games which should perhaps be separately categorized as "Demonstrations" or "Tests" rather than games, and belong as references in the Your Creations forum.
How can we preserve the integrity of the Arcade? We don't want people not to post complete but genuinely bad games, because that's nonetheless a "good-faith" effort. Is is truly best just to rate not-a-games 1-Star, or is there a more elegant solution?
