Unlocked both the Barnstorming TV commercial (which has quite a bit different graphics shown in the ad than what's in the game) and patch, both of which require finishing a certain game mode in under a set time.
For Games 1-3, this comes down to memorization of the set layout. Game mode 4 gives it some real replayability, as it randomizes the 25-barn level whenever you change to it. If you simply reset the game, the layout stays the same.
