Even though they were some of the more difficult levels, I always enjoyed the airship levels when playing Mario. They're just so different from the rest of the levels, even though that auto-scroll gets obnoxious. This awesome version of Bowser's airship by Nick Brick has all the necessary features: the cannons, the goofy propellers, and Bowser Jr.'s little flying machine. I really like how clean and polished this build is, it makes it feel very cartoony (and therefore accurate to the source material). It's very cool to see a 3-dimensional version of this ship.
