How it plays

You stand above the surface. Tap Cast line and the hook drops. From there the run plays out in two phases:

Descent. The hook falls toward the seabed 100 ft below. Fish swim across your path. Each time the hook bumps a fish (or a column wall) it's stunned for a beat — descent slows to a crawl. A descent timer caps the phase, so if you bump too many fish you don't reach the bottom and your catch ceiling shrinks.
Retract. Whether or not you made it all the way down, the line starts rising. New fish swim through the rising hook. The first ten fish you touch are caught. After ten, additional touches are ignored — choose carefully.

Scoring

Each fish has a base point value (small = less, large or rare = more). Your run score is:

score = round(sum(catch.base_pts) × clamp(depth_reached_ft / 100, 0.3, 1.5))

Cast deep and catch heavy. A shallow run with mediocre catches is worth a fraction; a max-depth run with the right ten is worth 1.5× the catalog sum.

Logging & anti-cheat

Every interaction — fish spawn, hit, near-miss, catch, phase change — is timestamped and posted with the run. The server keeps the full event log forever (per the platform policy) and uses the same Mulberry32 PRNG the client uses, so submissions can be re-simulated and scored independently in the future.
