I will build a branded HTML5 mini game or interactive product quiz
Moon C
About this gig
Turn your brand into an interactive experience. I build short HTML5 mini games and product quizzes for pop-up stores, events, product launches and campaigns. Players open a link or scan a QR code on mobile or desktop. No app installation.
BASIC: Rebrand one PLAYKIT game or quiz with your logo, colors, images and copy. One language.
STANDARD: A custom campaign game or product quiz with a branded result card, two languages and GA4 events. Up to two short stages using the same mechanic.
PREMIUM: A tailored game with up to three stages, three languages and an entry form connected to Google Sheets, Slack or a webhook. Consent text and fields are agreed before development.
All packages include responsive screens, design and animation, a test link, source code, final build and deployment to one compatible hosting environment. I test iOS Safari and Android Chrome.
Original illustrations, 3D models, multiplayer, accounts, payments, prize draws and hosting fees are excluded. Revisions refine the agreed scope; new mechanics are quoted separately.
Message me with your goal, audience, devices and launch date before ordering.

I am the founder of Nerdevs. I build AI workflow automation and interactive web content for small teams and brands.
For automation, I develop AI agents, API integrations, and approval workflows. I am building OpenDesk with Unity/C#, Python, and FastAPI.
For interactive content, I create responsive HTML5 games, branded campaign experiences, and real-time web apps. My work includes PLAYKIT's 10 browser games, Word Relay's classroom game, and banban's band site with live lyrics.
I handle planning, UX, development, testing, and deployment.

FAQ
What interactive content can you create?
Short branded HTML5 games and product quizzes for events, pop-ups, launches and campaigns. A typical flow is start, play and result. Basic uses an existing PLAYKIT template; larger or unusual ideas need a custom scope.
Will it work on phones and computers?
Yes. The game runs in a browser from a link or QR code, with responsive controls for mobile and desktop. I test iOS Safari and Android Chrome. Please discuss older phones, kiosks or in-app browsers before ordering.
Do I need a server or domain?
I deploy to one compatible hosting environment you provide, such as Cloudflare Pages, Vercel, Netlify or a web server. Hosting and domain fees are excluded. If you need me to host it, we can agree on a fixed period and a separate offer.
What data integrations are included?
Premium includes an entry form connected to Google Sheets, Slack or one webhook. We confirm fields, consent text, retention and access before development. A dashboard, leaderboard, phone verification or fraud prevention requires a separate scope.
What counts as a revision?
One revision is one consolidated feedback round within the agreed game, screens and branding. Basic includes 2 rounds; Standard and Premium include 3. New mechanics, extra games or a changed design direction need a separate quote. Agreed functional bugs receive 14 days of support after delivery.
Are illustrations, multiplayer or prize draws included?
Original illustrations, 3D modeling, multiplayer, user accounts, payments, native app publishing and prize draw operations are excluded. You provide licensed brand assets and copy. I deliver the source code and final build.
