Build THE LAST GATE: A Crowd Runner with Math Gates

Create a playable portrait crowd runner with math gates, real-time team-size changes, losses from obstacles, an end encounter determined by the number of survivors, three short routes, instant retry, and seeded input replay.

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.
