This appears to be a file name for an update patch (version 2.02.06.01) of the game , possibly from a scene release group (NSP indicating a Nintendo Switch package or a repack).
The phrase likely refers to in-game context — in A Little to the Left , you frequently organize household objects, and “helpful paper” might be a hint about a note, instruction, or clue included with the update (e.g., explaining new levels, fixes, or organizing puzzles).
