Preview checklist

Test the complete experience as a first-time player.

• The opening screen explains the action, goal, and progress.
• Actions give clear feedback and there is a restart or recovery path.
• Intended input methods work; touch controls are comfortably spaced.
• Small-screen text, portrait/landscape layouts, and browser overlays leave controls usable.
• Images and audio load; the first action is ready when the start screen appears.
• Returning from a background tab works; slow loading provides feedback.

Use a fresh browser session to avoid cached assets or saved preferences. This checklist complements product-specific device and integration checks. Finally, test the published link after stopping the local server.
