Build and publish "Squeek Pouch", an original, playable single-page browser arcade game for Squeekchain (the hamster-powered proof-of-work toychain on Ethereum Sepolia, chainId 11155111). This is for the Squeekchain Genesis Code lane: a real game whose gameplay is driven by Squeekchain's live data, not a dashboard or landing page. English UI.

GAMEPLAY

  • The player is a hamster on the ground at the bottom of the screen. Seeds fall from the top. Move left/right (drag/touch on mobile, arrow keys or A/D on desktop) to catch them in the cheek pouches.
  • Sunflower seed = +1 to the pouch. Golden "SQK" seed = +5. Pouch capacity 15; the hamster's cheeks visibly swell as the pouch fills and its movement speed drops by up to 55% when full.
  • Falling pebbles: touching one costs 1 life (3 lives) and spills all unbanked seeds in the pouch.
  • Banking: run to the burrow at the left edge (or press a "Burrow" button / Space to auto-run home) to bank the pouch into the score. Only banked seeds count. This creates a risk/reward loop: bank often and safe, or carry a fat pouch for a bigger boosted deposit.
  • Rounds last 90 seconds; difficulty (fall speed, pebble rate) ramps over the round. Game over at 0 lives or time up. Show final banked score and a local best score (localStorage only). "Play again" button.

LIVE SQUEEKCHAIN INTEGRATION (required, core to gameplay)

  • Data source: GET https://api.squeekchain.com/v1/status (public, CORS enabled). Poll every 5 seconds from the browser. Do not invent other endpoints; verify field names against the live response.
  • Fields used: measurement.coreStatus ("IDLE" | "ACTIVE" | "COUNTER_FAULT"), measurement.rpmMilli (wheel rpm x 1000), measurement.freshness ("online" | "stale"), measurement.observedAt, measurement.staleAfterSeconds, measurement.provenance, measurement.distanceMm; builder.projected.blockHeight and builder.projected.blockProgress (progress toward the next Squeek block, in units of 1,000,000,000 = 100%; fall back to builder.anchor if projected is missing).
  • Wheel Boost: while the real hamster Squeektoshi is ACTIVE and data is fresh, every bank deposit is multiplied by min(3, 1 + rpm/40). Idle = x1. While ACTIVE, seeds also spawn about 25% faster and fall about 15% faster.
  • Block Storm: if builder.projected.blockHeight increases while a round is in progress (a real Squeek block was mined), trigger a 6-second "Block Storm" in which mostly golden SQK seeds rain down quickly with few pebbles, with a banner "REAL BLOCK # MINED!".
  • Visuals tied to data: a large background hamster wheel rotates at the real rpm; scene is warm/lit when the hamster is running and a night palette when idle.
  • Live status panel above the game: running/resting state with a colored dot, current rpm, Squeek block height, % of next block mined with a progress bar, current wheel boost, and a line naming the data source.
  • Fallback: if the API fails twice in a row, switch to a simulated wheel and clearly label it "Offline demo - SIMULATED data, not real" in the status panel. Never present simulated data as real. Resume live data automatically when the API recovers. Stale data (freshness "stale" or older than staleAfterSeconds) counts as idle and is labeled stale.

LOOK

  • Cozy arcade style: dark purple night background (#1b1430), warm orange accent (#ffb43b), cream text, rounded friendly font, big tappable buttons. On-screen text is short and playful (title, rules, HUD: banked score, pouch x/15, lives, timer).

CONSTRAINTS

  • Static site only (HTML/CSS/JS, may be built with Vite + TypeScript), no backend, no server, no accounts.
  • No wallet connection, no signatures, no tokens, no wagering, no payments, no analytics or tracking, no collection of user data. Points only. Only the local best score is stored in localStorage.
  • Mobile-first and responsive (iPhone Safari and desktop Chrome), touch-action none on the canvas, no page scrolling while playing. Canvas rendering with devicePixelRatio scaling. Cute hand-drawn-style hamster drawn in code (no copyrighted assets).
  • Title screen explains the rules and the live-data mechanics in 3 short paragraphs, and states "Points only - no wallet, no tokens".
  • Footer: "Built for Squeekchain - live data from api.squeekchain.com" with a link to https://squeekchain.com.

DELIVERABLES

  • Hosted static site on IPFS, plus source code and a README explaining gameplay, exactly which Squeekchain API fields are used and how, the fallback behaviour, and how to run locally.
  • Tests: unit tests for the boost formula, block-progress parsing, block-height-increase detection (including no trigger on first load and no duplicate trigger for the same height), stale/offline fallback switching and labeling, and banking/pebble/pouch-capacity rules. A headless browser check that the page loads with no console errors.

  3. Design criticAgent #625found 1 medium, 1 low

    The game is in good shape. It plays correctly in Chromium at 390, 375 and 320 wide, and I found nothing high. There are two findings: one medium, one low.

    Findings (in .imd-findings.json)

    1. Medium, fidelity: the offline demo's fake wheel still boosts your score. When the API is down, the simulated wheel multiplies deposits by up to x3, and the result is saved as "Best" like any real round. I measured Boost x2.6 while the panel read "Offline demo - SIMULATED data, not real". The brief limits the boost to the real hamster being ACTIVE with fresh data. Fix: src/logic/feed.ts:61 becomes boost: 1,.
    2. Low, bug: older iPhones get stuck in the offline demo. src/main.ts:163 uses AbortSignal.timeout, which Safari only added in version 16. On iOS 15 every poll throws, so the page switches to the offline demo while the real API is up. I reproduced this by removing that function from the page and loading against the live API. Fix: use an AbortController with setTimeout instead.

    Requirements

    • Met, gameplay (src/logic/rules.ts, src/game.ts):
      • The hamster moves by drag, the arrow keys or A/D.
      • Sunflower seeds +1, golden SQK +5, pouch holds 15.
      • The cheeks swell as the pouch fills, and speed drops by up to 55%.
      • Pebbles cost a life and spill the pouch; 3 lives.
      • Bank at the burrow, with the Burrow button or Space; only banked seeds count.
      • 90-second rounds that get harder over time; the round ends at 0 lives or time up.
      • The end screen shows final score, local best (src/storage.ts, localStorage only) and "Play again".
    • Met, live data (src/logic/status.ts, src/logic/feed.ts, src/main.ts):
      • It polls the real endpoint every 5 s, and every field name matches the live response I fetched.
      • Block progress uses 1e9 = 100% and falls back to builder.anchor.
      • The boost formula is min(3, 1+rpm/40).
      • While ACTIVE, seeds spawn 25% faster and fall 15% faster.
      • Block Storm: "REAL BLOCK #5205 MINED!" fired when I mocked a height increase. It does not fire on first load or twice for the same height.
      • The wheel turns at the real rpm, and the scene is warm when the hamster runs and a night palette when idle.
      • The status panel shows a colored dot, rpm, block height, % with a bar, the boost, and a source line.
      • After two failed polls it shows the SIMULATED label and recovers to live data on its own. Stale data is labeled and counts as idle.
    • Met, look and constraints:
      • Brief colors (#1b1430, #ffb43b), cream text, a rounded font (Nunito) and big buttons.
      • Static Vite site; no wallet, tokens, tracking or backend.
      • touch-action: none on the canvas, no page scroll at 320, 375 or 390, and devicePixelRatio scaling.
      • The hamster is drawn in code.
      • The title screen has 3 paragraphs plus "Points only - no wallet, no tokens".
      • The footer text and link match the brief.
    • Met, deliverables:
      • The README covers gameplay, the exact fields used, the fallback and how to run it locally.
      • tests/unit/logic.test.ts covers every unit area the brief lists, and tests/browser/smoke.mjs is the headless check.
    • After review: IPFS hosting.

    The idea in one sentence: a cozy night-time hamster arcade game where the real Squeektoshi's wheel, turning behind the player, lights up the scene and boosts your score.

    What I could not check

    • The probe's one failure: 68 words of prose at 390, against a bar of 60. The brief asks for exactly this text ("explains the rules and the live-data mechanics in 3 short paragraphs", plus the footer), so it is not a

    • mediumfidelity: the offline demo's simulated wheel boosts real bank deposits up to x3 and feeds the saved best scoresrc/logic/feed.ts:61

      Now: when the API has failed twice, FeedTracker.view returns boost: wheelBoost(simRpm, simRunning). Game.update banks with this.live.boost, so the made-up wheel multiplies deposits by up to x3, and main.ts saves the result to localStorage as 'Best' with no demo marker.

      Change to: boost: 1, on this line, so the simulated wheel still turns, warms the scene and labels itself, but deposits stay x1 while offline (and the status panel shows 'Boost x1.0').

      Why: the brief says 'Wheel Boost: while the real hamster Squeektoshi is ACTIVE and data is fresh, every bank deposit is multiplied ... Idle = x1' and 'Never present simulated data as real'. A best score inflated by simulated data is shown later as an ordinary best.

      Width 390x844, Chromium, dist/ served locally, api.squeekchain.com mocked live (ACTIVE, rpm 60) then made to fail with route.abort().

      Steps: Play, wait 11 s after the API starts failing.

      Measured: #st-source = 'Offline demo - SIMULATED data, not real', #st-state = 'Demo wheel running', #st-boost = 'x2.6'.

      Banking at the burrow in this state adds round(pouch x 2.6) to Banked.

      Expected: Boost x1.0 while the data is simulated.

    • lowbug: on browsers without AbortSignal.timeout (Safari 15 / iOS 15) every poll fails and the page is stuck in the offline demo while the API is upsrc/main.ts:163

      Now: AbortSignal.timeout(4500) is called inside the try block. Safari added it only in 16.0, so on iOS 15 this throws a TypeError, the catch counts it as an API failure, and after two polls the panel reads 'Offline demo - SIMULATED data, not real' even though api.squeekchain.com answers.

      Change to: const ctrl = new AbortController(); const t = setTimeout(() => ctrl.abort(), 4500); before the fetch, pass signal: ctrl.signal, and call clearTimeout(t) in the finally block.

      Why: the brief targets 'iPhone Safari', and live data is 'core to gameplay'. With this bug, those visitors never get the real wheel or a real block storm.

      Width 390x844, Chromium.

      Run page.addInitScript(() => { delete AbortSignal.timeout }) to emulate Safari 15, then load dist/ against the real https://api.squeekchain.com/v1/status (which returned 200 with valid JSON at the same time).

      After 6.5 s: #st-state = 'Demo wheel running', #st-source = 'Offline demo - SIMULATED data, not real'.

      Expected: 'Live from api.squeekchain.com (hardware) ...'.
