How smoothly the camera follows the player. 0.2 = default, 0.1 = minimum (near-instant), 1.5 = extra smooth. Affects camera position, tilt, and mode transitions.

Camera field of view in degrees. 50 = default. Lower = zoomed in, higher = wider perspective.

Slides the camera sideways so your character sits off-center on screen. Negative = character left of center, positive = right. 0 = centered (default).

Slides the camera vertically so your character sits above or below screen center. Negative = character lower, positive = higher. 0 = centered. Default: -50.

(Mouse, Touch & Gamepad) How much input is needed to switch lock-on targets. Lower = more sensitive (easier to switch), Higher = less sensitive.

While locked on, raises the camera so your character sits below screen center while the locked target stays centered. 0 = off, leaving the framing to Camera Offset Y. Default: 0.

Color of the small dot marking your locked-on target. White stays readable over any enemy color; Cyan matches the rest of the HUD. Default: White.

Show the dot marking your locked-on target. Off hides it completely and overrides everything, including the Show/Hide UI toggle. Lock-on itself keeps working. Default: On.

Color of the thin ring marking what your next attack would hit. White and Cyan match the reticle colors; Red is the original hostile-tinted look. Default: White.

Show the thin ring marking what your next attack would hit. Off hides it completely and overrides everything, including the Show/Hide UI toggle. Default: On.

Horizontal mouse turning and camera sensitivity (0.001 = very slow, 0.003 = default, 0.009 = very fast).

Vertical mouse camera sensitivity (0.001 = very slow, 0.003 = default, 0.009 = very fast).

Orthogonal Stick Mode (Touch & Gamepad): Angle (degrees) from straight forward before turn input triggers (5-30°). Higher values create a wider "go straight" zone in discrete stick mode. Applies whenever the left joystick uses discrete 4-direction control — Free-Camera Left Joystick Mode set to Orthogonal, or on gamepad when Horizontal Directionality is disabled.

(Touch & Gamepad) When enabled, the camera joystick's vertical axis controls rise/dive while locked-on to an enemy, with horizontal input still switching targets. The vertical zone is ±22.5° minimum, expanding based on target switch sensitivity. Needs a stick to read a held direction from, so it applies to the gamepad and to the touch Camera Joystick — not to swipe-to-look, where a horizontal flick switches targets instead.

Deadzone percentage for the gamepad's left stick (15-50%). Higher values require more stick movement before input is registered.

Deadzone percentage for the gamepad's right stick (15-50%). Higher values require more stick movement before input is registered.

Linear: Direct 1:1 mapping. Exponential: Squared/Cubic response curve for finer control at small movements.

Controls how aggressive the exponential ramp is for gamepad joysticks and triggers. Squared (x²): Default. Cubic (x³): Finer control at low inputs.

Direction controlled by left trigger (LT).

Off: Disabled. Binary: Full on/off. Ramp: Analog pressure-sensitive.

Direction controlled by right trigger (RT).

Off: Disabled. Binary: Full on/off. Ramp: Analog pressure-sensitive.

Assign an action to each D-pad button for play mode. Assigned wheels, attacks, dodges, heals and skills behave exactly like their fixed bindings.

(Touch) Joysticks: fixed movement joystick and rise/dive knob (or camera joystick) in the bottom corners. Floating Zones: touch anywhere in the bottom-left area to move — a thumb knob appears under your finger — and the bottom-right area to rise/dive. Swiping open water moves the camera under either layout; Floating Zones simply has no room for the optional camera joystick. Nothing is shown until you touch.

(Touch) Floating Zones only: cuts each zone's inner-top corner diagonally, freeing a triangular notch of open water at the bottom-centre — swipe to look, tap to attack there. Width is the notch mouth at the top of the zone band as a percentage of screen width; Depth is how far it dips toward the bottom edge as a percentage of the band height. 0 on either = uncut rectangular zones; 100/100 = the zones become triangles meeting at a point. The zones tint briefly while adjusting.

(Touch) Floating Zones only: makes the invisible capture zones visible. On Touch: a landing near a zone's open-water edge briefly glows the edge around your finger. Near Edge: the glow follows your finger whenever it strays near the edge mid-drag — past it, the glow parks where you crossed — and a touch that just misses a zone lights the edge it missed. Always: both zones stay tinted full-time. Opacity sets the tint strength for every mode; Glow Size is the reveal glow's radius in pixels; Glow Duration (ms) is how long a landing or near-miss glow holds before fading — lifting the finger fades it early, so high values mean the glow simply remains while held.

(Touch, play mode) Drag the wheel buttons, lock-on button, heal/skill edge buttons — and in the Joysticks layout the sticks themselves — anywhere on screen. Elements that overlap are highlighted red while editing; overlaps are allowed, just not recommended. Each Touch Layout keeps its own arrangement, and anything you haven't moved keeps following its classic solved position (including the Button Position choice). Reset returns the current layout's elements to those defaults.

Arrangement of the two wheel buttons and the lock-on button relative to the joysticks. Edges: the wheels split apart — each sits above the surface in its own bottom corner (joystick, rise/dive knob, or the corner itself under Floating Zones) — with the lock-on button on its own at screen centre. The tags above show which of the three buttons follow the arrangement and which sit at custom spots from the HUD layout editor (this layout only). Choosing an arrangement — or tapping RE-APPLY — returns all three to it; everything else keeps its custom spot.

(Touch) Adds a right-hand joystick for the camera. Swiping open water always moves the camera, with or without it — the joystick is a second surface, not a replacement. A finger that stays put is still an attack tap; one that travels becomes a camera swipe. While locked on, the joystick takes over target switching and swipes stop changing target. Unavailable with Floating Zones, which has no room for it.

Adjust the size of the right joystick. 1.0 = default size. For other UI elements, see HUD Scale in the Accessibility tab.

Simulates physical joystick spring resistance near the edge (0-100%). At 0% (off), finger-to-knob movement is 1:1. Higher values require more finger travel to reach maximum position, mimicking analog stick resistance.

(Touch) Deadzone percentage for the camera joystick (15-50%). Higher values require more stick movement before input is registered. Requires the Camera Joystick.

(Touch) How the Camera Joystick's vertical axis is read: Binary snaps to full strength once past the deadzone; Ramp scales smoothly with distance from centre. Affects photo-mode camera pitch. Requires the Camera Joystick.

(Touch) How far the camera turns per pixel of swipe (0.001 = very slow, 0.005 = default, 0.012 = very fast). Applies to both axes.

(Touch) The rise/dive pill that takes the bottom-right corner whenever the camera joystick is off. Scale sizes the pill (1.0 = default). Deadzone is the dead band around the centre detent (6% by default — deliberately smaller than a joystick's, since nothing rests on the knob). Requires the Camera Joystick to be off.

Adjust the size of the left joystick. 1.0 = default size. For other UI elements, see HUD Scale in the Accessibility tab.

(Touch) Deadzone percentage for the movement joystick (15-50%). Higher values require more stick movement before input is registered. Applies to the fixed stick and the floating-zone stick alike.

Linear: Direct 1:1 mapping. Exponential: Squared/Cubic response curve for finer control at small movements.

Controls how aggressive the exponential ramp is for touch joysticks. Squared (x²): Default. Cubic (x³): Finer control at low inputs.

Maximum time window (in milliseconds) between taps to register as a double-tap. Lower values require faster taps.

When off, use two-finger tap to heal manually. When on, automatically heals from school fish based on health: every 10s above 50%, every 5s at 25-50%, every 3s below 25%.

How to trigger manual healing. Edge Button: the + button above the left joystick. Tap Health Bar: hides the edge button — you instead tap the health bar at top left to heal.

How to activate equipped skill. Edge Button: the button above the right-hand touch surface (the camera joystick, or the rise/dive knob). Tap Stamina Bar: hides the edge button — you instead tap the stamina bar at top left to activate.

(Play mode) Cancel every drone's remaining respawn wait right now, in all maps. Drones in the map you are in return straight to their patrol zones; drones in other maps are waiting for you when you arrive. Takes effect immediately, even while paused.

(Play mode) The above, plus every dead NPC fish. Fish in the map you are in swim back through the portal together; fish in other maps reappear scattered across their roam bounds. Dead recruits return wild — you will need to recruit them again. The enemy fish is left alone deliberately: it is knocked out rather than dead, and picks itself back up after about 10 seconds.

(Play mode) Save where you are standing and looking right now — map, position, facing, camera angle and zoom — as the benchmark vantage: a fixed recording spot for performance comparisons. Setting again overwrites it. Survives reloads.

(Play mode) Return exactly to the saved vantage, so recordings taken days apart share the identical view. Works while paused. If the vantage is in another map you travel there like a portal — a recruited school stays behind. Waves still re-roll on every play entry; the vantage pins where you stand and look, not the water.

(Play mode, needs a saved vantage in this map) The fixed scenario as one press: go to the vantage, settle, measure 30 s calm, spawn the Dummy Drone, wait for it to engage, measure 60 s of fight, put it away — three times over. Press it, then resume: it starts on the first unpaused frame. Don't touch the mouse or keys until the button says DONE; keep the browser window on top and the console undocked, or the report will say so. The report prints to the console with every frame attributed (flare lit vs dark, freezes with the compile tell, the held-fixed conditions) and lands in localStorage 'benchmark-last'. Console: tuneBenchmark({repeats, calmSeconds, fightSeconds}); pressing again mid-run cancels.

(Play mode) Press 9 to record per-frame fish orientation data — position, velocity, heading, ring ups, bank, camera — for diagnosing visual bugs from a real reproduction. Press 9 again (or hit the 90s cap) to stop and download the JSON. While this is on, the recorder owns the 9 key; while off, the key is free.

(Play mode) Press 1 to spawn a static practice target in front of you — targetable by every attack, invulnerable, immovable, never aggros anything. Press 1 again to put it away. While this is on, the dummy owns the 1 key; while off, the key is free. Turning this off puts a spawned dummy away.

(Play mode) Press 2 to spawn a full-AI practice drone ahead of you — it chases, shoots, lunges and takes hits like a real drone, but refills instead of dying. Press 2 again to put it away. Only works in maps that run the drone system (the Shallows today). While this is on, the drone owns the 2 key; while off, the key is free. Turning this off puts a spawned drone away.
