How to Play Shanghaivania Ink Sans Fight Simulator
In Shanghaivania Ink Sans Fight Simulator, players take on an energetic, standalone alternate-universe boss battle created by community developer Ink_Sans58. The encounter draws inspiration from Shanghaivania, a renowned musical and conceptual crossover that infuses the dramatic melodies of Touhou Project with Undertale's Megalovania. Stepping into the arena as Chara at LV 20 with 99 Max HP and active Karma Retribution (KR), you face Ink Sans as he unleashes an unpredictable flurry of paintbrush strikes, custom ink bones, and high-velocity Gaster Blasters. Players looking to explore multi-phase encounters can also try Ink Sans Fight Simulator.
To begin playing, click the central launch icon inside the game container to initialize web audio and open the main title screen. The interface displays the opening lineup with Ink Sans brandishing his giant broom-like brush. Once the battle begins, steer your red SOUL through the combat box using either the Arrow Keys or WASD keys. Unlike conventional turn-based encounters where the player repeatedly chooses actions from a bottom menu, this simulator delivers a continuous, high-octane bullet-hell survival gauntlet spanning 24 consecutive attack waves.
During combat, you must adapt to sudden environmental shifts and surprise guest hazards. Mid-fight, a swirling purple dimensional portal opens, summoning Jevil into the arena to barrage you with diamond spreads and giant scythe beam slashes. If you want to practice dedicated evasion against Jevil's chaotic attacks, you can also check out Jevil Fight Simulator. Surviving Shanghaivania requires managing your Karma drain, tracking blaster charge cues, and maintaining fluid movement across the entire box.

About Ink_Sans58's Shanghaivania Project
Shanghaivania originated within the Undertale AU music community, conceived by composer Troff and popularized through dynamic fan animations and remixes that blend ZUN's "Septette for the Dead Princess" with Undertale's iconic boss themes. Ink Sans—the protector of alternate universes created by Comyet—fits naturally into this multidimensional musical setting with his artistic flair and fluid combat style.
Developer Ink_Sans58 explicitly established several critical design choices for this project: it is the author's own unique, standalone take on the Shanghaivania concept. The developer made clear that this project is not a prequel to the original Shanghaivania animated battle, nor is it a sequel to existing multi-phase Ink Sans games. It features the energizing "Shanghaivania Phase 3 Theme" throughout the fight, but structures the entire encounter as a single unified 24-attack endurance challenge rather than dividing the battle into separate phase-select menus.
The developer's credits reference several community contributors, including --Shiran-- for foundational bone engine mechanics, monaki for star projectile assets, and various AU character inspirations. Notably, while the project credits acknowledge multiple AU figures, the actual in-game combat features Ink Sans as the primary adversary, accompanied by an authentic surprise incursion from Jevil (via the Purple Hole sprite) and Dust Sans thematic effects. Other credited characters, such as Cross Sans, do not actively participate in the combat sequences.
The author also documented known technical characteristics of this version: HP numbers are rendered using dynamic clone stamping, which can occasionally produce slight visual misalignment during heavy screen shake, and dying on the very first wave can occasionally require a clean restart from the toolbar. Understanding these version-specific behaviors helps players appreciate the game's distinctive community craftsmanship.
Attack Sequences, Jevil Hazard, and KR Mechanics
Rather than utilizing a selectable phase menu, Shanghaivania Ink Sans operates as a continuous progression through 24 scripted attack patterns. Understanding the core hazards and mechanics is essential for reaching the finale:
Paintbrush Sweeps and Ink Bones: Ink Sans wields his signature oversized paintbrush, launching custom black and multi-colored ink bones (`Ink Bone`). These projectiles slide along the floor and walls, frequently splitting into secondary fragments or firing secondary warning flashes before accelerating across your path.
Gaster Blaster Variations: Ink Sans deploys several distinct blaster configurations throughout the battle:
• Standard Blasters: Traditional skull blasters that charge with a white spark before firing wide vertical and horizontal beams.
• Homing Blaster Beams: Specialized blasters (`sans gaster blaster shot homing`) that track your SOUL's coordinates prior to locking their firing angles.
• Smash Bros Blasters: Rapid-fire blasters that appear around the box perimeter to discharge rapid, alternating laser volleys.
The Jevil Incursion (Purple Hole & Scythe Beams): Mid-way through the battle, a swirling purple rift (`Purple hole`) manifests near the top of the box. Jevil appears (`bouncyJevil`), initiating a chaotic crossover sequence:
• Diamond Barrage (Attack 18): Spinning rings of diamond card suits rain downward across the box, demanding continuous circular dodging.
• Jevil Scythe Knife (Attacks 19, 22, and 24): Massive curved scythe blades (`Jevil Knife`) sweep across the entire width of the arena, projecting colossal beam trails that divide the arena into narrow safe strips.
Karma Retribution (KR) Drain: With 99 Max HP at LV 20, the battle incorporates authentic KR poison physics. Colliding with any projectile does not merely deal flat impact damage; it applies Karma poison that drains your health by -0.05 HP per tick as long as contact persists, making prolonged obstacle overlap rapidly fatal.
Survival Tips for Shanghaivania Ink Sans
- Toggle the F Key to Monitor Frame Rates: Pressing F toggles an integrated real-time FPS counter in the upper portion of the screen. Dense blaster spreads and multi-layered particle effects can cause brief browser frame drops. Watching the FPS indicator helps you time your dodges accurately during intense visual waves.
- Prepare for Jevil's Purple Hole Telegraph: Watch the upper boundary of the combat arena closely. When the swirling purple portal (`Purple hole`) appears, Jevil is about to manifest. Shift your SOUL downward toward the center floor to prepare for incoming diamond rings and wide scythe knife sweeps.
- Minimize Contact Time to Mitigate Karma Drain: Because the game applies KR poison draining -0.05 HP per frame, grazing obstacles or getting pinned against the wall is catastrophic. If a hit is unavoidable, quickly steer straight through the projectile into open space rather than lingering inside its hitbox.
- Test Both WASD and Arrow Keys for Movement Comfort: The game maps SOUL movement to both Arrow Keys and WASD simultaneously. Depending on your keyboard hardware and finger dexterity, WASD may provide cleaner diagonal inputs when steering through spinning diamond matrices.
- Stay Grounded During Paintbrush Bone Waves: Ink Sans' paintbrush sweeps launch projectile sprays that originate from the upper canvas. Position your SOUL near the bottom third of the box, where bone gaps are widest and give the longest visual reaction buffer.
- Use the Web Toolbar Restart After Opening Deaths: As documented by developer Ink_Sans58, dying during the opening attack sequence can occasionally cause the reset routine to loop. If you fall early in the battle, simply click the Restart button on the top player toolbar for a fresh, immediate retry.
