The 38 Studios guys left a few minutes ago. I showed our game off to them, and they all seemed fairly impressed. They had good suggestions for improvements, but my concern is that I'm not sure how much I want to add at this point.
I even convinced a couple to play it, and they had about the reaction I was expecting: that they had fun, and that the game appears deceptively simple. They way it works now, it takes a few times playing through it to realize the winning strategy. They tried what they thought would work, but found that by the time they made real progress, they were running low on time.
So, I'll plunk around with it a bit more, but the good thing about this game jam is that I can devote the whole weekend to it. I'm not sure how much time I'll get to devote to it in addition to all the schoolwork I still left to do. And the trick part is, the deadline for the contest is just before classes end for the term, so I can't have any free time after class to polish the game. But that's okay.
