TIDE is a lightweight, human-readable format for writing branching conversations.
It was developed for The Sardine Identity but is flexible enough for any adventure game.
TIDE scripts use simple blocks and commands to encode dialog, narration, conditions, and options - making it easy to draft, read, and expand dialog trees without engine-specific tools.
This document proposes and defines a format to write the game's dialogs in. That way, the dialogs can be written not unlike in a screenplay, but still offer a tree-like structure.
