According to me, it's was a cool jam, the teme was good, and the time too.Four week, it's very good to make a game.
It's true, the people was very quiet (me the first, due to lack of time) but I am sure that in future editions (if there are any) there will be more activity!
Yes, in my last jam, Retro Remake jam, People talk often and games have had a lot of feedback ;D.
Do you want make a video of all game for this jam? :D
