Gameplay

A hybrid 2D world: top-down life at the sanctuary, side-view diving in the ABYSSAL, and close-up surgery at the healing table.

Side-view diving

Oxygen is the only clock

Every dive is a vertical descent. The camera follows Mira down through parallax layers of water while her oxygen drains — faster the deeper you go. Find injured creatures, collect trash, and make it back to the surface before the tank hits zero.

▸Oxygen bar: blue → yellow → red → blinking. At 0%: panic ascent, and you lose your catch.
▸Depth meter: shows the current zone — pressure and darkness rise together.
▸Rescue slot: one creature per dive. Choose your patient wisely.
▸No mid-dive saves: surfacing or blacking out ends the run — a light roguelite touch.

Underwater

The Rescue

Panicked animals aren't enemies — they're patients that don't know you're here to help. Yet.

Approach

Stealth-like. Loud movements raise the creature's panic — move slow, stay calm.

Diagnose

Get close enough to scan. The scan reveals the injury and which tool you'll need.

Treat

An underwater minigame based on the injury — cut the net, remove the hook, wipe the oil.

Stabilize

Channel for five interruptible seconds to secure the patient in your rescue net.

Transport

The creature follows you slowly. Drift too far away and its panic climbs again.

Panic & Trust

Panic rises with loud movement, wrong tools and nearby aggressive neighbors. At 50% the minigame gets harder, at 75% the creature flees, at 100% it lashes out — costing you oxygen, never health. Calming spray and slow behavior bring it back down.

Trust grows with every successful treatment, correct meal and release — and shrinks with failed minigames, wrong tank temperatures and neglect. High trust makes every future treatment easier.

Back at the sanctuary

The Healing Table

Top-down, hands-on surgery. You move the tools — no abstract menus.

Scalpel

Click & drag a line to cut free and set stitches.

Tweezers

Grab hooks and shards, then pull them gently out.

Syringe

Hold on the wound for exactly the right dosage.

Sponge

Scrub in circles to wipe away oil and grime.

Time & weather

One day, twenty minutes

Storms strand creatures on the beach. Red tides block zones but push rare patients into safe water. Every day asks a different question.

Morning · 06–12

Best visibility. Feed patients, clean tanks, prep the dive.

Noon · 12–16

Strong sun, lively coral, extra plankton — slight oxygen regen.

Evening · 16–20

Golden hour. Rare creatures wake up.

Night · 20–06

Too dangerous to dive. Base phase: care, craft, sleep.
