The former is just a level where you have to use several springboards to get across long gaps C-3 literally does nothing but add a Lakitu that will make the first half of the level more difficult, which is lazy to be a level of bonus worlds that are supposed to be prizes for passing the game eight times. 7-3 and C-3 are almost identical, and the theme is also the same.Because when you jump in the springs, you throw yourself very high in the sky, which means you can't see well where you're going to fall, with a great chance that you'll fall into a bottomless pit and lose a life, the worst thing is that the levels are almost focusing on just spring jumping, so you're very likely to get a Game Over if you have very few lives.In general, these levels are a terrible idea, as the springs throw too high into the sky and the controls are still too rigid and heavy, which makes landing on platforms difficult.The controls are even worse at these levels as controlling Mario when he's in the air is often vague and can cause you to lose a life or even get a Game Over, In addition, platform sections are tedious to complete like most silverforming sections.For starters, these levels feel somewhat flat, because all you have to do is jump over springs worrying because there's a good chance of falling into bottomless pits, plus on the platforms it's infested with enemies and in C-3 in the first half of the level, there is a Lakitu that will chase you as you jump over the springs, making this level artificially more difficult.These levels are known for their big difficulty and mediocre level design, and are often considered the worst levels of Super Mario Bros.: The Lost Levels.
