Stilted Into but minimalistic gameplay

Behind the stilted intro, there's actually a pretty thin one-scene shooter. There's a guy who resembles a bear, who's firing the bees out of a bazooka (Rusty Ivan, I presume), standing on the nearby building's rooftop (let's call him a bazooka-bear). Our hero's mission is to shoot dead all the bees from the scene, until there's none left. At that point our bazooka bear retreats, and the player moves to the next level. Except for a different background image, there's nothing new on the higher levels. Even the hardness level stays the same, which is odd. The graphics is very colorful and interesting, but the gameplay is repetitive and not well-thought through as we would expect from the introduction.
