Great game
Just beat it. For those of you stuck on Tin Can, focus on getting the boomerang and the lightsaber on the first shot. This is pretty easy. Now the top of the "can" is open, so try to rack up as many baloons with the boomerang as possible. Again, this should take a few tries. Try aiming a little high of the box. Finally, pick up the remaining baloons with the final dart. Takes some luck, but is definately doable.
Great job on a great that's actually fun for more than 5 minutes!
