Rocketmen goes for a campy feel with its presentation and mostly succeeds. Character designs look like they jumped right out of an old sci-fi serial like Buck Rogers, creating a fun aesthetic. The game uses a cel-shaded look that carries over between story presentation and gameplay areas. Comic book panels are used to tell the story that is ruined only by the writing. The story is okay considering the concept, but it tries too hard to be funny. Jokes are forced and overdone, especially the "Martians are dumb" jokes. The first time Martian technology is explained, it's funny, but it gets old quickly.
Voice acting doesn't do much to help the dialogue either. All of the characters either come off as lazy, incompetent, assholes or some combination of the three. Considering the way the story is presented, it probably would have been better to skip the voice acting.
