I don't know why so many people are having trouble with Chrome. I have never had a game that hasn't worked because I was in Chrome. Just make sure you're browser and flash are current.
Anyone notice how the tanks at the end of the game look suspiciously like the AAT from Star Wars? That and the fact that also at the end theres tons of flying Boba Fetts all over the place makes me feel like this takes place in the Star Wars Universe and the worm is some rebel ploy. (Which works fantastically)
