Phoenix Wright: Ace Attorney - Trials and Tribulations

If the keyboard does not respond, click the game screen first and check the actual key mappings in the player controls. Arrow keys scrolling the page can mean the game does not have input focus.

On a phone, check whether the player provides touch buttons. Try landscape or fullscreen if the controls are too small. After connecting a gamepad, press a button with the game focused and check whether the player recognizes it.

For a black screen or a stalled load, wait briefly before using Reload player or Browse games in the embedded player or play page. Reloading restarts the player and may lose unsaved progress. If no save option is available, do not rely on refreshing to preserve progress.
