HTML5 Canvas Interactive Demo — Browser Game for Your SiteAI KAISEI GLOBAL
I build lightweight, embeddable HTML5 canvas experiences for marketing sites, product launches, and portfolio proof — vanilla JavaScript, no engine lock-in.
Live proof: https://ship-project-kappa.vercel.app/demon-gate/
(Full 30-stage action game I shipped — same stack I use for client work.)
What you get
• Custom interactive demo or mini-game for your brand
• Vanilla JS + Canvas — deploys on Vercel/Netlify/static host
• Mobile-friendly controls, performance-tuned (Lite mode option)
• Clean handoff: source + short customization notes
• Optional: embed inside your existing Next.js LP
Good for
• Agencies wanting a playable hero instead of a looping video
• SaaS founders needing a memorable product launch moment
• Brands targeting Japan or global — I handle EN/JP copy if needed
Process
Scope call (15 min) — mechanics, art direction, timeline
Build + share staging URL
Revisions round + deploy support
After launch
Optional monthly retainer ($200–400/mo) for tweaks, monitoring, and small feature batches.
Message me with your site URL and what interaction you have in mind.
