How to Vibecode Your First Roblox Game with PromptBlox

Open Create, review your available allowance, and choose the build quality that fits your first version.

Light is a useful choice for a focused first game. Medium adds planning and detail, High gives demanding maps and gameplay dedicated attention, and Ultra supports ambitious worlds with connected systems. Build levels are not plans, but your plan decides which levels you can choose: Free and Lite use Light, Pro adds Medium, Max adds High, and Ultra and Ultra+ add Ultra. For this walkthrough, start with a compact crystal-garden adventure.

Write a brief that connects the setting, player action, goal, feedback, and restart rule.

Create a crystal garden in the ruins of an observatory. Players find three different glowing crystals and bring them to a central telescope. Show collection progress and count each crystal once. When the set is complete, light up the telescope and open a viewing platform. Offer a restart. Connect each area with broad stone paths and use blue crystals, brass details, and mossy walls.

Make it yours by changing the setting and reward. Use the Prompt Guide if you want help turning a rough idea into a more detailed brief.

Send the prompt and watch the live activity and developing scene in the workspace.

PromptBlox coordinates work on the world and its gameplay. V2 pays closer attention to connected paths, recognizable landmarks, and usable objectives. Follow the observatory’s formation and send direction in chat when you want to steer a detail; the workspace shows how your request is handled.

Review the starting area, crystal routes, telescope, and viewing platform in the browser scene.

Look for a telescope that players can recognize from the start and paths that visibly connect the collection areas. Where enabled in your workspace, Game Graph can help you explore the objects and systems behind the scene. Pick one change that brings the garden closer to your idea.

Name the area or behavior to improve, describe the result you want, and identify the parts to preserve.

Make the telescope easier to find from the starting area. Give it a tall brass base and a blue banner, and add route signs at the path junctions. Keep the crystal locations, collection rule, and viewing platform.

Read the refinement summary and review the result. Library lets you return to saved drafts, and History gives you access to saved versions. If a stopped build has retained progress, use the continuation option shown in the workspace with available allowance.

Use Export to download the saved scene and scripts as a .rbxlx file, then open it in Roblox Studio.

Keep the export identifiable so you know which version you are testing. Studio runs on supported Windows and Mac computers; use Roblox’s setup guide if you need to install it. You can inspect and customize the exported objects and scripts as you learn.

In Studio, collect the crystals, complete the telescope, visit the platform, and restart the activity.

Also revisit a collected crystal and check that it counts once. Roblox’s testing modes help you check movement, interactions, and the intended controls. Bring any specific issue back to the saved project’s chat, then test the revised export. Keep manual Studio edits in a separate working copy because they do not automatically update PromptBlox.

Publish the ready version through Roblox Studio, choose its audience, and invite eligible testers using Roblox’s current requirements.

Our publishing guide walks through the handoff. Ask a tester which landmark helped them and where they needed a clearer clue. That feedback gives your next PromptBlox refinement a purpose, whether you improve the existing garden or add another discovery.
