How it works

A ProximityPrompt shows the button when a player is close, with the right key or button for their device.
A BillboardGui keeps the speech bubble facing the camera above the head.
nextLine % #LINES + 1 goes back to the first line after the last one.

Make it yours

Show each player their own lines: This shows the same bubble to everyone nearby. For one player at a time, or for choices, ask the script generator.
