Since it's taking longer than I thought it would, I'll tell you what's going on with Ducky Builder level building bit. . .
Basically, we're gonna have an official Gamedev.net Ducky Builder level-building contest. It's taking some time to set up because I'm gonna have some pretty substantial prizes, and I want to have all of the prizes lined up and ready to ship before starting the contest. Basically, I don't want you to be frustrated by a prize taking months to get to you, and see the previous paragraph if you're wondering why I'm having trouble getting the prize-fund together. If things go the way I want, this contest will have more prizes than any other contest that gamedev's ever had.
I will, however, give you a bit of a head start if you're interested. Click below to get the latest Ducky Builder (1 meg ZIP file).
It might go through a change or two before the contest, but it's basically in release-able form. Go ahead and play around with it. Maybe get started on your official magnum opus contest entries. If you find a bug or have a suggestion, lemme know. Just press F1 for help if you need it, but it's pretty easy to use.
