Ink and Inky
Narrative · Non-AI workflow
A · Branching narrative inside another engine
A strong fit for branching relationship stories inside an existing game engine. Ink keeps the writing in text, and Inky lets you play through choices as you edit, so you can work on the dialogue before connecting it to the game.
You still need to connect Ink's story runtime to your game's interface and systems. For a small Ren'Py project, that extra narrative dependency may add more integration work than it saves.
