We've already got ten submission for the game jam, which is making me extremely happy.

Just a reminder about one rule, though, quoted below.  If your game is for sale during the voting window, it will be removed from the jam with extreme prejudice.

By submitting my game, do I give up any rights to my work? No.  Your game is your game.  However, you may not charge for your game jam game during the submission or voting window.  Once voting is closed, if you want to sell your game, feel free.  If your game is for sale during the voting window, your game will be immediately removed from the competition.
