klish was certainly the most polished game at the NYC/Columbia site of the Global Game Jam. It's a little level-based Flash game in which your mouse pointer is a repulsor, pushing other screen objects away; you use it to herd them around. Your goal -- well, this is an almost immediately intuitive game. You will figure it out very quickly. Six levels, each of which will probably take you no more than a minute to play. I list the download site above, but it's a freely distributable swf, so it's also embedded here.
It's a little thin a present, but you can see how this might well be extensible to a more fully-featured game; and indeed, I have an email from the developers indicating that they plan to do so, so you may one day see a much bigger version on the free Flash game sites.
Oh, there's no 'restart' code in the game, so to play again, you'll need to reload the page.
