I played around with it a bit a few years ago, not affiliated.

Ink is a markup language rather than an engine, so it plays nice with version control and managing huge stories. It also lets you handle variables and do some pretty complex logic inside the scripts.

This also this means you can integrate it with different workflows, dialog authors can editor and focus on dialog in the inkle editor. Then push their changes into a game built in Unity.

Definitely more suited to big teams than Twine which is more targeted at solo indie devs.
