I’m building Lolmao.Io, a 2D online sandbox inspired by Pixel Worlds that lets players build, chat, trade and fully customise their avatars. The core loops, monetisation model (Pixel Pass plus in-game currency) and a detailed design document are already in place; what I need now is solid game development muscle to turn those plans into a playable PC experience. Scope of work • Set up a client-server architecture that supports real-time multiplayer in large, persistent worlds. • Implement core gameplay systems: block placement & removal, avatar movement, chat, trading and basic crafting. • Create a simple account/login flow tied to cloud-saved inventories. • Integrate placeholder art so we can iterate quickly; final graphics will be added later. • Build hooks for the Pixel Pass and virtual-currency store (no payment SDKs yet, just the stubs). Tech notes I’m engine-agnostic—Unity, Unreal, Godot or something custom is fine as long as it reliably hits 60 fps on mid-range PCs and can be exported to Web or Mobile later. Use whatever networking stack you’re most comfortable with; just outline why it suits a 2D MMO. Deliverables 1. A working pre-alpha build for Windows (.exe) with a hosted test server. 2. Source project with clear folder structure, commented code and setup instructions. 3. Short README describing engine version, third-party libraries and build steps. Acceptance criteria • Up to 50 concurrent players can join the same world, place/remove blocks and see others’ actions in real time with <150 ms latency. • Chat, trading and inventory persist across sessions. • Pixel Pass and currency UI paths are reachable, even if they point to stub logic for now. If you love crafting multiplayer sandboxes and are ready to move fast, let’s talk—I’ll share the full GDD and we can agree on milestones right away.

Hi, I'm Osama from Virginia. You need a playable 2D MMO sandbox pre-alpha for PC, and the priority is stable real-time multiplayer with clean systems that can grow into Web and mobile later. I can help turn your design into a working client-server game without unnecessary complexity, while keeping the codebase organized for future expansion. I have direct experience with Unity, networking/API-driven apps, and cloud-connected systems. For this project, I’d first review your GDD and existing setup if you already have one, then choose the most practical networking approach for a 2D persistent world, implement movement, block editing, chat, trading, inventory saving, and add stub flows for Pixel Pass and currency. I’d also make sure the project structure, build steps, and server setup are clear for testing. Since this is an existing concept with specific performance goals, I’d like to confirm the expected world size and whether you prefer a Unity-first path for the fastest pre-alpha delivery. I’m available to start anytime. Let’s talk details. Regards, Osama
