Cross-Platform Dress-Up World Development

I’m building an online dress-up universe inspired by classics like IMVU and MovieStarPlanet, only updated for today’s audience. The experience must run smoothly in a browser and as a dedicated mobile app so players can jump between devices without losing progress.

Core experience
Players start by choosing a realistic 3-D avatar, then refine every detail. To make this feel truly personal, the avatar creator needs three fully supported customization layers:
• Clothing & accessories
• Hairstyles & hair colors
• Body features & skin tones

Game loop & progression
I’ll supply the creative direction and item lists; I need you to build the underlying systems: an inventory, a virtual shop, and a points/XP economy that rewards dressing challenges, social interactions, and daily log-ins. Achievements should automatically trigger level-up animations and unlock new wardrobe tiers.

Technical expectations
• Single codebase that outputs WebGL/HTML5 for browsers and native builds for iOS/Android (Unity or a comparable game engine is fine)
• Secure user accounts with cloud save and cross-platform syncing
• Modular architecture so new clothing lines or events can drop in without patching the entire app

Deliverables
1. Prototype with one gender-neutral base avatar, starter hairstyles, and twenty clothing items
2. XP and leveling system tied to an on-screen progress bar
3. Admin panel or script that lets me bulk-import new wearable assets
4. Documentation covering build pipeline, asset specs, and how to expand the wardrobe

If you’ve shipped avatar-centric games before and can demonstrate clean, scalable code plus an eye for fashion detail, I’d love to see your approach and timeline.
