Tempted to buy it now you've reminded me. Sorry about hijacking the topic, but quick question:
It says the game will be removed from the app store on January 1st... doesn't this mean if we delete the game from iTunes it'll be impossible to get back? Bit of a sucky move if you ask me. If they want to stop people buying it they should just stick a ridiculously high price tag on it and let 'em complain.
Edit: to make up for the hijack, here's the answer:
Highlight:You have to shoot the ice balloon in the middle, so that the dart bounces off the frozen one and rebounds onto the reindeer balloon. Then move the reindeer through middle where you aimed your first dart and hit the lightsaber balloon.
