I’m putting together a very early, stripped-down open-world game in plain JavaScript and need a working prototype that focuses on a single loop: gather a resource, place a block, repeat. Think of it as a tech test rather than a content-heavy build—the world can be a simple infinite plane, placeholder textures are fine, and elegance in the code is more important than visual polish at this stage. You’ll receive two items from me the moment we start: a concise design brief and a PDF containing reference sketches that define the minimalist look and UI flow. The PDF also shows how I’d like the building and crafting actions to feel, so please follow that as the style guide. Here’s what I need back: • A browser-ready project (HTML, JS, CSS) that boots without additional tooling. • Basic first-person or over-the-shoulder movement with WASD and mouse. • A simple inventory/hot-bar, drag-free, for placing or removing predefined blocks. • A flat or procedurally extending terrain that accepts the blocks anywhere on its surface. • External asset folder so I can swap textures or models later, plus clean, well-commented code. If I can download the files, open [login to view URL], move around, place blocks, and see no console errors, the milestone is done.

Hi I understand you need a minimal open world prototype in plain JavaScript with a single gather and place loop. I will deliver HTML JS CSS files that start with WASD mouse movement, a simple hot bar, and an infinite flat terrain that accepts block placement. Code will be clean commented and assets placed in an external folder for texture swaps. My recent Three js work and years of software development let me finish this within your budget in about five days. Do you prefer first person or over the shoulder camera perspective Will the terrain be a static plane or generated as the player moves Do you need mobile touch controls later Let me know if a short demo build would help

Hello. I have built similar browser-based JavaScript prototypes involving 3D movement, interactive environments, inventory systems, and block/object placement, with a strong focus on clean, maintainable code rather than unnecessary visual complexity. Could you confirm whether you prefer first-person or over-the-shoulder movement, and whether the PDF sketches define any specific interaction details such as block selection, placement/removal, or crafting behavior that must be followed exactly? Your answers will be a great help in understanding the intended feel, and I’ll keep the implementation simple: browser-ready HTML/CSS/JS, procedural/flat terrain, responsive movement, hot-bar inventory, block interaction, external assets, and zero console errors. I can start immediately and will treat this as a focused technical prototype, delivering a clean foundation that is easy to expand into the larger open-world game later. Let's discuss this project further. Best regards, Jeff Chong.
