I shipped a small browser game called Toon Tone Color: a 5-round color memory challenge where you read a cartoon-inspired prompt, adjust HSB sliders, submit a guess, and get a score card at the end.

Why I made it:

I wanted a lightweight game that works instantly in the browser.

The interaction is simple enough for mobile: read a prompt, tune hue/saturation/brightness, submit.

The result card is generated client-side, so players can copy and share it without uploading their gameplay data.

A few implementation notes:

Built with Next.js 15, TypeScript, Tailwind, and Cloudflare Workers.

The first version is free and does not require signup.

Analytics only load after consent; the gameplay state is kept in browser localStorage.

The site is fan-made and not affiliated with any cartoon, anime, game, comic, studio, or entertainment brand.

The part I am watching…
