Cloud City 4-29 is the twenty-ninth level of Cloud City. To pass this level with three stars, you should pop all pigs and score at least 82,000 points.
Send Lando into the steam; Lando himself will end up going through the top-right structure. A split second after launch, shoot the leftmost pig with Lando’s blaster. The lasers can ricochet into the suspended platform, and onward through the chains on the far right. The laser shot is very challenging.
