Virtuoso Victory: Streamer ‘Dr. Doot’ Conquers the Brutal ‘Hollow Knight: Silksong’ Using an Electric Saxophone

In a stunning display of skill, dedication, and unconventional instrumentation, a Twitch streamer known as Dr. Doot has achieved 100% completion in the notoriously difficult Metroidvania sequel, ‘Hollow Knight: Silksong,’ using an electric saxophone as his primary game controller. This incredible feat, which took the streamer 92 hours of live-streamed gameplay, is the latest entry in the world of extreme challenge runs and has quickly become a sensation in the gaming news cycle.

Released on September 4, 2025, by Team Cherry, ‘Silksong’ was already setting a new benchmark for difficulty in the platforming genre, with developers citing main character Hornet’s increased speed and skill as a reason for more complex and intelligent enemy design. Dr. Doot’s use of a modified Aerophone (an electronic wind instrument with a saxophone key layout) elevates the perceived difficulty from ‘brutal’ to ‘borderline impossible,’ turning every jump, dash, and needle strike into a coordinated musical performance.

The Mechanics of ‘Dooting’ Through Pharloom

The success of the run is attributed to a custom control setup that links musical inputs to game actions. The electric saxophone’s keys and pressure sensors are translated into PC inputs using software like Bome MIDI Translator. The instrument features a small analog stick, known as a ‘mod wheel,’ on the back to control Hornet’s movement, while the various notes and key presses trigger actions like jumping, dashing, healing, and combat maneuvers.

Technical Challenges of the Saxophone Controller:

• Precision Input: Unlike a standard gamepad or keyboard and mouse, the Aerophone is highly sensitive. Dr. Doot revealed that the system sometimes registers unintended inputs—even from sloppy playing—which could spell instant death for Hornet during the game’s more merciless boss fights and platforming segments.
• Endurance and Focus: The 92-hour run demanded extreme physical and mental endurance. Complex enemy encounters, such as the infamous gauntlet in the High Halls or the True Final Boss, require constant, rapid, and accurate musical notes to control the character, effectively forcing the player to master two demanding skills simultaneously.
• High-Value Content: The sheer novelty and difficulty of this challenge have driven significant Twitch viewership and high engagement, making the term ‘Silksong Saxophone’ a valuable, high-traffic search keyword for gaming content and streaming revenue.

More Challenging than ‘Elden Ring’? The True Hard Mode

Dr. Doot is no stranger to souls-like challenges, having previously completed games like ‘Dark Souls 3’ and the gargantuan ‘Elden Ring’ using the same unconventional controller. Interestingly, the streamer stated in post-completion interviews that ‘Silksong’ was not, in fact, the most challenging game to beat with the sax; that title belongs to the recent Soulslike title ‘Lies of P.’

This comparison only further highlights the technical mastery and immense skill required for this feat. The Metroidvania genre, particularly one as focused on fluid, precise movement and tight combat windows as ‘Silksong,’ presents unique gaming challenges that test reaction time to the absolute limit. Successfully traversing spike-filled nightmares, reminiscent of the original ‘Hollow Knight’s’ Path of Pain, while physically playing an instrument, has solidified Dr. Doot’s reputation as a top-tier challenge runner.

The Culture of Extreme Gaming

This achievement is the latest highlight in the vibrant culture of extreme video game challenges, where players constantly seek the most inventive and difficult ways to complete a game. From ‘no-hit’ runs of the hardest bosses to utilizing peripherals like bongo drums, dance pads, or, in this case, an electric saxophone, these runs showcase the dedication and creativity of the gaming community. They also generate huge digital marketing and affiliate marketing opportunities around high-demand gaming titles.

As the ‘Silksong’ community continues to grapple with the base game’s difficulty, Dr. Doot’s successful 100% completion provides a humorous yet inspiring counterpoint. It proves that no gameplay mechanic is too complex, and no game controller is too absurd when matched with a truly dedicated and talented player. Fans are now eagerly awaiting the streamer’s next impossible task, with hints already dropping about a 100% Steel Soul speedrun (the game’s permadeath mode) for the future.
