Start with a playable loop
Describe what the player does, what pushes back, and what counts as success in one short session.
Build a 3D game around one playable idea
Choose a place, a player goal, and one mechanic to test.
Start with a compact 3D level: give the player somewhere to go, one challenge to solve, and clear feedback when they succeed. Try the first build, then tune movement, camera, and pacing.

How it works
From a 3D game idea to a playable test
Keep the first pass small enough to play. Use what happens in the test to decide which part of the level needs work.
- Pick the player goal
Choose one thing the player should do
Name a simple objective such as reaching a door, finding a landmark, or moving an object onto a switch.
- Set the scene
Describe the route and camera
Give the level a few landmarks and say what the player should see while moving through it.
- Add one mechanic
Make the challenge testable
Choose one interaction—jumping, pushing, or avoiding a hazard—and keep unrelated systems out of the first pass.
- Play the first build
Watch where the design gets unclear
Try the route and check whether the controls, objective, and feedback make sense as the player moves.
- Tune one detail
Make a focused revision
Adjust one part of the level, then play the same section again to see whether the change helped.
Pick a starting point
Choose a 3D game idea to try
Start with a platform route, an explorable space, a physics puzzle, or a compact arena. Each prompt gives you one design question to test.
Build a short platforming level
Give the player a clear route across a few jumps, with a checkpoint before the hardest gap.
Prompt
Create a compact third-person platform game set across rain-wet rooftops at dusk. Give the player responsive jump controls, three safe platforms, one wider gap, and a checkpoint before the final leap. Use distant city lights to show the route. End the level at a marked rooftop door.
- A route with a visible endpoint
- One checkpoint before the hardest jump
- Camera framing that keeps the next platform in view
Jump, land, and reach the exit ↗Why SEELE
What to focus on in a first 3D build
Make the space easy to read
Use landmarks, lighting, and camera placement to show where the player can go next.
Test one mechanic at a time
Keep the first level focused on movement, physics, or a single encounter so playtest feedback points to a clear change.
Give controls a clear purpose
Tie each action to a visible result, then check whether players understand it without extra explanation.
Check the experience in play
Ask a player to try the level and note where they hesitate, miss a cue, or lose the route.
Tune the next pass
Adjust one thing—such as jump distance, camera angle, or enemy timing—then test the same section again.

Who might use a 3D game prototype
A small prototype can help explore a level idea before a team invests in a larger build.
Solo developers blocking out a 3D level
Use a short route to explore layout and movement before spending time on more rooms, props, or story.

Plan a 3D game with a prompt or an engine
A prompt can help frame the first playable question; the engine workflow is where teams set up and refine a project.
| Feature | SEELE AI prompt | Manual game-engine workflow |
|---|---|---|
| First step | Describe a small scene, the player goal, and one mechanic to try. | Choose an engine project and set up a scene for the same goal. |
| Level layout | Use a short route and a few landmarks to make the first playtest legible. | Block out geometry, camera, and navigation in the project. |
| Mechanic test | Focus the brief on one interaction, such as jumping, moving an object, or avoiding a hazard. | Implement the interaction and tune it against the intended controls. |
| Playtest question | Check whether players understand the objective and notice the feedback. | Observe the same playtest and record where the design needs adjustment. |
| Next iteration | Change one design detail and compare the next attempt with the first. | Revise the scene or mechanic in the engine and playtest again. |

FAQ
3D AI game maker questions
What is a 3D AI game maker?
A 3D AI game maker starts from a written game idea and helps shape a first playable direction. The result still needs to be tried and reviewed against the project goal.
What should I include in a 3D game prompt?
Describe the scene, what the player is trying to do, one mechanic, and how success should look. Add a camera view or visual style when it affects the playtest.
Can I make a 3D game without writing code?
You can begin by describing the game in plain language. Check the current editor for available generation and editing options, and review the result before relying on it in a project.
How do I plan a small 3D level?
Give the player a visible objective, connect a few landmarks with a clear route, and add one challenge. Test whether a new player can tell where to go next.
How can I test a 3D game mechanic?
Build a short section around one mechanic, such as jumping or moving an object. Watch a player try it and note whether the action and its result are clear.
What kind of 3D game can I prototype?
The examples on this page cover platforming, exploration, physics puzzles, and arena encounters. Choose the one that best matches the mechanic you want to examine.
How do I make 3D game controls easier to understand?
Keep the first control set small, show a clear response to each action, and test the controls with someone who has not seen the design before.
How should I use landmarks in a 3D game?
Place landmarks where they help players recognize the next route or destination. Check that lighting and camera framing keep the important cues visible.
How can I improve the camera in a 3D game?
Test the camera along the whole route, especially at jumps, turns, and narrow passages. Adjust it when it hides the next action or makes distance hard to judge.
Can a prompt create a complete 3D game?
A prompt is a starting point for exploring an idea. Review the generated result for missing content, control issues, and project requirements before treating it as complete.
Can I export a 3D game project?
Available project and export options can depend on the current workflow. Check the options shown in the editor and confirm that the output fits your target engine before planning a handoff.
Which game engine should I use for a 3D game?
Choose an engine based on your target platform, team experience, and project needs. Confirm any required formats or integrations in the current product documentation.
How much does it cost to generate a 3D game?
The displayed cost can depend on the selected model and generation task. Review the current Koin balance and cost in the editor before starting a run.
What should I review before sharing a 3D prototype?
Play through the main route, check controls and feedback, and confirm that assets and project settings fit your intended use. Fix blockers before sharing the build.
