Developer Reports Building Mountain Mogul With Claude Code in 11 Days
The Mountain Mogul developer reports using Claude Code to build a live browser-based 3D ski-resort game over roughly 11 days. The project reportedly includes a roughly 14,000-line HTML file using three.js, 63 automated test scenarios in headless Chromium, Supabase-backed cloud saves and 169 commits. The developer handled design, testing and visual judgment, while Claude Code wrote code, updated tests, debugged using saved data and deployed releases through GitHub Pages.
The project provides a concrete, publicly accessible example of Claude Code supporting coding, testing, debugging and deployment for a released game, although the developer’s productivity and contribution claims remain self-reported and unverified.
