[Showcase] Mappyn — Retro-based Habbo in HTML5 | Next.js + Bun + Pixi (own engine)

[UnkHabboBR]

Hey RageZone! I'd like to share Mappyn, a Habbo-based hotel I'm building with a custom engine, no Nitro, no Arcturus, no third-party client. Both client and server written from scratch on a modern stack.

Stack
- Front: Next.js 15 (App Router) + Pixi.js — custom isometric renderer
- Server: Bun with a custom WebSocket protocol (binary via MessagePack, end-to-end validation)
- DB: PostgreSQL + Drizzle ORM
- Avatars: modular composition compatible with Habbo's format (figuredata/figuremap/draworder) + in-game look editor

What's already working
- A* pathfinding movement, rooms, heightmaps and isometric depth-sorting
- Avatar editor (figure string), catalog and inventory
- Full furniture: place / rotate / push, pixel-perfect picking, shortcuts (ctrl = pick up, shift = rotate)
- Dimmer lighting, beds (sit & lay from both sides), ball physics (kick, dribble, ricochet)
- Limited rares (LTD) with serial numbers and an anti-bot purchase queue
- Pets with server-side AI, atomic trading, messenger, badges, likes and visits
- Houseke pdng panel, admin commands alert, :kick, :ban), in-game bug reports
- Security done right: JWT revocation, per-connection rate limiting, WebSocket hardening
