Offline PWA

Build a lightweight browser-based interactive experience using Babylon.js, packaged via PWA Builder, and deployable to a subfolder on an existing website.

A working prototype of the core game logic will be provided as a reference. The objective is to recreate the same behavior in a clean, modular Babylon.js architecture suitable for production.

Scope:

Body-map style home screen with clickable zones

Two to three playable levels

Real-time character movement and opposing entity behavior

Simple health / damage system

Collectible items affecting state

Environmental hazard with limited fail condition

End-of-level completion animation

Review screen with tap / hover-to-enlarge interaction

Visual state change on home screen after level completion

Simple privacy notice modal

Technical requirements:

Must work optimally on mobile devices with touch controls and smooth performance

Fully functional offline after first load

Proper manifest and service worker setup for PWA Builder compatibility

Optimized asset size and performance

Static production build suitable for subfolder hosting with relative paths

Clean, modular architecture for future expansion

Delivery includes full source code and production build folder
