Pretty funny for a long fart joke.
At first I thought it was kinda dumb, but when Chewie started painting the Death Star walls (not to mention the Storm Trooper's armour) a rich fecal brown, I almost added a few pounds myself. There was no interactivity and the violence was limited to the moist splatter of a turd against some shiny white armour, but that wasn't the function of the piece, so it was served well. The graphics coulda been a little better, but overall it was pretty funny for a long fart joke.
