I've also wondered this. This jam is my whole teams first game making experience and we are very very happy with what we made, however it hasn't gotten much traction. It seems like it would be very helpful to do a publicity push right away as it likely snowballs like you mentioned which we failed to do for the first ~40 hrs and now we are way behind the curve, but I guess I know for next time.
Anyways I've subed to the thread so hopefully someone drops some info, and I'll try out your game. Best of luck.
