3D Browser Remake of Video Game

I need a faithful 3D recreation of the entire game shown in this video: https://www.youtube.com/watch?v=Igh4QhpT81w. Every feature, level, mechanic, and character that appears there has to make it into the browser version so players feel as if they are stepping straight into a three-dimensional copy of the original.

Platform
The game must run smoothly inside a modern web browser—no installs, just click-to-play. A WebGL export from Unity or an equivalent HTML5 framework such as Three.js or Babylon.js is fine, provided performance remains solid on standard desktop machines.

Visual & Audio Fidelity
All characters, environments, animations, UI elements, and sound effects should match the video as closely as legally possible. Where assets need to be rebuilt from scratch, keep proportions, colors, and timing identical so returning players instantly recognize every detail.

Core Expectations
• Full gameplay loop, including every power-up, enemy pattern, scoring rule, and level transition
• Responsive controls mapped for keyboard (WASD/arrow keys) and mouse where appropriate
• Consistent frame rate at typical desktop resolutions
• Clean, maintainable code and clearly organized project files

Deliverables
1. Playable Web build hosted on a test URL
2. Complete source project (Unity, Three.js, or similar) with all assets and documentation
3. Brief setup guide for local builds and future updates

I’ll supply additional reference captures once development begins and will test each milestone directly in the browser.
