DEVICE: A Photorealistic 3D Puzzle Game That Uses the Smartphone Itself

Comprehensive instructions for creating a photorealistic, portrait-mode Android 3D puzzle adventure in Unity, where players investigate a black, cube-shaped device called DEVICE. In addition to touch controls, integrate the phone’s tilt, rotation, face-down gestures, accelerometer, camera, microphone, vibration, speaker, brightness, compass, charging status, and other capabilities as puzzle inputs within the same game world. The linked article publishes these development instructions in full as entered into ChatGPT Work, and also introduces the 25-stage DEVICE demo and its Android APK.

Prompt optimization tips

1

Specify editability

State which objects must remain separate, named and editable; otherwise a visually convincing shell may still be unusable.

2

Close the test loop

Ask the model to run the scene, inspect visible failures and repeat until concrete frame-rate, interaction and layout checks pass.

3

Stage long builds

For large worlds, split the work into districts, assemblies or milestones and approve each section before expanding scope.

Imagine It. Shape It.
