Touch: tap an isle to select it, then tap an action (Survey, Build Lab, Supply, Quarantine, Deploy Cure); tap End Week to advance. Mute and pause are top-right. · Keyboard: number keys 1-9 (or Tab) select an isle; S survey, L lab, U supply, Q quarantine, C cure; Space or Enter ends the week; P or Esc pauses; M mutes. The mouse clicks everything the touch UI exposes.
About:
A turn-based containment strategy, in the spirit of the 2000s board-and-Flash outbreak games but inverted: you are the archipelago's defender, not the disease. Each week you spend a few action points across the isles. Readings are uncertain — an isle you haven't surveyed lately reports a fuzzy estimate that can hide a bloom, and when an unsurveyed isle erupts the Council is blindsided and trust drops hard. Surveys buy you the truth for a few weeks, supplies raise a shield that both blocks and treats, labs pour research into a one-time cure that knocks an isle down, and quarantine seals an isle's shipping lanes at the cost of its income and the public's patience. The wind has a direction and a strength each week and swings from week to week, so the bloom spreads fastest downwind across open lanes — a forecast warns you a storm week is coming. You lose if the Council loses faith, if the archipelago is overwhelmed, or if the season ends with the bloom still burning; you win by quelling every isle, and you are rated on how much trust you kept and how early you finished. Five hand-built maps escalate from a four-isle tutorial to an eight-isle, two-bloom gauntlet with a jittery Council: First Light, Crosswinds, The Narrows, Stormseason and Full Bloom, each unlocked by clearing the last. The simulation is a deterministic fixed step — one call advances exactly one week, and all weather and report noise are a hash of integer coordinates, so a map plays as a fair, repeatable puzzle. Everything, the art and the sound included, is drawn and synthesised in code with no image or audio files.

Phone check: 2026-10-03: the deterministic sim has node tests (node verify.js all): identical replay across all five maps and seeds; 300 fuzzed games all terminate with no out-of-range state; a human-like report-driven bot wins First Light/Crosswinds/The Narrows/Stormseason 100% and Full Bloom 82%; and losability is proven (do-nothing loses every game, panic-lockdown collapses trust 20/20, and the overwhelm, trust and timeout loss reasons are all reachable). In the browser: real CDP touch on a portrait phone (390x844) and landscape (844x390), and mouse and keyboard on a 1280x800 desktop — title and scenario select, tap-to-select and act, End Week, a full win and a loss with one-tap retry, pause on a hidden tab, resize between orientations, and a run with localStorage blocked. Zero console errors and no network requests. Audio was rendered offline through the same synthesis code against an OfflineAudioContext and measured: no noise floor (silence RMS below -200 dBFS), music sits about 13 dB under the SFX, the peak stays near -12.6 dBFS even with every cue stacked, every cue carries under 12% of its energy above 6 kHz, and no single sound drones.

Lemon StallRun a tiny street-corner drinks stall for a fourteen-day summer fair. Read the forecast, buy lemons, sugar, ice and cups, mix a recipe, set a price, then watch the street decide, and learn from a hindsight chart of what every price would have earned.
Word BugsTrace a path across touching letters to spell words and strike the ink pests crawling over a living page. Every pest shows its hit and the beats until it strikes, so you choose what to spell and who to aim at. Five chapters, longer words hit harder, and a five-letter word leaves a charged tile behind.
Beetle ParadeA line of beetles is marching down a garden trail toward the burrow. Flick beetles into the line from your snail; three of a colour scuttle off, and the gaps snap shut into chain reactions.
Bloom FourDrop linked elemental seeds into a narrow garden, matching four or more of a kind to make them bloom. Blooms collapse the garden, chaining into fresh matches and burying your rival in thornpods. Duel a three-tier AI or climb an endless, quickening solo run.
