As a complement: alternatively, you can also use the Karma ordering (click ‘More options’ on the lower-left panel of the entries page), which favours games according to how many games the author has rated/commented over how many votes he received. (Some people try to game the system by leaving a lot of copy-pasted comments, but you can check someone’s comments quickly using their personal page.) There is also a special page (the link is at the top of the entries page, only shown to those that can vote) for games with few votes.
I am under the impression that not that many people know about the Karma ordering (I think there should be an effort both from the site and the main game jam pages to promote it), but it is useful (and inspired by Ludum Dare’s own system, by the way). Anyway, have a good testing-reviewing session!
