I'll start this board with a game that I never got around to post to the old GosuUsers page, my entry for the 11th tri-annual Ludum Dare game development competition, link to the final blog posting here:
http://www.ludumdare.com/compo/2008/04/20/final-8/The link also has screenshots and download links for all platforms (and an awkward development timelapse). The game hasn't been updated afterwards, so there's still just nothingness after you beat it.
TODO: The download links are all broken right now, for many of my LD games actually. I love this one entry very much and will make sure to re-upload them as soon as I am happy with the Mac app wrapper again.
