This is World 1-1 from the game Super Mario Bros, appearing as though it had aged 30 years.
This is a side-scrolling stage, where players start from the beginning of the level to the flagpole at the end, before it loops back to the beginning. Alternatively, players can fight on World 1-2. Players from the start of the underground level till the end, but instead of having players take the pipe, it leads players to the Warp Zone, where the stage eventually loops.
