I turned browser cookie counts into game currency - meet Crumbongo

Crumbongo started from a pretty stupid little question: What if the number of accessible cookies on the website you're visiting could become game currency? So I built it. Crumbongo is a tiny local Chrome game where you choose a website, let the extension count the accessible cookie records for that site, and turn only that number into game rewards. No cookie names or values are used for gameplay. From a tiny experiment to an actual little game The first version was basically: choose a website; check its accessible cookie count; harvest that number into a Cookie Jar; spend the cookies on Bongo. Then I kept building on top of it. Crumbongo now has: a level and progression system; pixel-art cosmetics; multiple habitats; companions; local statistics; Monkey Climb; Cookie Stack. The whole thing still lives inside a Chrome extension popup. The technical side Crumbongo is deliberately small. There is no React, TypeScript, Vite, game engine, backend or framework involved. It's built with: vanilla JavaScript; HTML; CSS; Chrome Extension APIs; requestAnimationFrame for the minigames; chrome.storage.local for persistent game progress. The minigames are built with regular DOM elements and CSS rather than Canvas. That constraint became part of the fun: figuring out how far I could push a tiny extension popup without turning the project into something much larger. Local by design Because the core mechanic involves browser cookies, I wanted the privacy model to be extremely clear. Crumbongo requests access one site at a time. For gameplay it only uses the number of accessible cookie records returned for that site. It does not: store or transmit cookie names; store or transmit cookie values; modify or delete browser cookies; use an account system; use analytics or tracking; send gameplay data to a backend. Game progress stays locally in the browser. The game-design part became more interesting than I expected Once I added progression, I realized the cookie mechanic could support mu
