Foghorn Bay

Tap to sound the foghorn; ships within range steer toward the blast, so time the blasts to guide a fleet safely into harbor.

Core mechanic

Tap to fire the foghorn in the current tap-direction; nearby ships adjust their heading toward the sound; route them past rocks to the dock.

Controls

Tap one of four directional zones around the lighthouse to sound the horn in that direction.

Theme

Misty nautical chart with a brass lighthouse, tiny wooden schooners, and stylized sea stacks.

Why now

Nautical micro-games are quiet on the charts; using audio-direction as the input is a fresh sensory hook.

Hook
5/10

Audio-as-input directional hook is genuinely novel, but the lighthouse-keeping-with-ships premise has already been shipped (Lighthouse Keeper II explicitly: 'lighthouse stopped working, help ships reach the port and dock, beware of pirates'), so the thematic wrapper is taken.Lighthouse Keeper II on Amazon Appstore has near-identical premise — help ships reach port via the lighthouse.Static Dread: The Lighthouse (Steam, Aug 2025) — lighthouse keeper guides ships using a radio, same core loop.

Virality
5/10

Four-zone directional taps are visually clear for short-form video, but the puzzle is contemplative rather than slapstick or fail-compilation friendly; no clear 'moments' to clip.Direction Dash shows directional-tap hypercasuals can stream, but ship-routing reads as slower / more cerebral than reflex-dashers.

Simplicity
7/10

Trivial to prototype: one screen, four tap zones, ships with simple steering AI, obstacle avoidance. No art complexity beyond stylized water/ships.GameRefinery confirms hypercasual norm is very simple controls and short sessions, which this fits.

Monetization
4/10

Single-core puzzle with no natural IAP loop; Q1 2025 industry data shows the market has moved from pure ad-driven hypercasual to hybrid-casual with meta layers, which this idea lacks.InvestGame Q1 2025 report documents the hyper→hybrid shift and the need for meta/booster layers to monetize.AppMagic notes subgenres are being reworked for IAP-viable loops, which a one-mechanic puzzle would struggle with.

Whitespace
4/10

Direct comparables exist: Lighthouse Keeper II (Amazon Appstore) ships the same 'help ships dock from a lighthouse' loop, and Static Dread: The Lighthouse (Steam) uses the same lighthouse-keeper-guides-ships mechanic. Only the tap-direction+foghorn skin is fresh.Lighthouse Keeper II — same lighthouse-to-harbor ship guidance premise already on mobile stores.Static Dread: The Lighthouse — Steam title, same lighthouse keeper / ship guidance core, indie publisher Polden.Lighthouses and Ships on Google Play shows lighthouse/ship theme already occupies a mobile puzzle slot.
