Hi @daves42 –
If you have not yet done so, I suggest looking at CSIDE, as an IDE interface, for Choice Script. The issue with using any engine is that you’ll need to understand the coding of that engine, at least in concept, before you will be able to fully lay out your game satisfyingly.
You have already used twine, so an IDE interface should be comfortable to use; once you grasp the language itself.
Many text processors (such as notepad++) have IDE plug-ins that you would be able to use. I know many published authors go this route.
Some people even utilize in-depth writing tools like Scrivener to write a story in a more traditional manner as well.
Lastly, there are many visual mapping tools out there (some for free as well) that can help you.
There are threads available on the forum that should be helpful, such as:

Good luck
