Build a focused game jam idea with AI

Build One Button Lighthouse, a game jam prototype featuring one-button timing game redirecting a lighthouse beam to guide ships. Focus on one central mechanic, a tiny level set, an explicit ending, and a realistic jam scope. Define movement and interaction controls, readable feedback, a clear success condition, an understandable failure state, and a restart button. Begin with one complete playable scene and avoid unnecessary menus or paid purchases. Include a short controls explanation and a pause option. Use original characters, environments, and audio placeholders; do not copy protected brands. Test the core loop, collisions, scoring where relevant, and the ending before expanding the scope. Hold one button to slow the rotating beam and release it to speed up; illuminate each approaching ship before it reaches the rocks, then end after three successful rescues. Keep the first run under five minutes and make the central rule express a jam theme. Provide a compact checklist for the organizer’s AI policy, asset credits, and submission build testing.
