You definitely should post it next time if you're going to be teh ruler of it.
only thing that rlly comes to mind is vioneT said they were avoiding the concept of 'winning' so it would feel more open to more people. But I'm just saying that for teh history. Run it in your own style how you want. I think it was usually average 2 people made generators for the generator jam. Maybe your style with it being winnable will appeal to more people. Or less people. Who knows :)
