Hey there!
I'm a writer who absolutely loves the way the interactive media of games changes a narrative.
This seems like an interesting project. If I could get a bit more background information, I could probably get you a writing example more suited to this sort of game, as most of the writing for games I'd been working on so far has been artistic or satirical in nature.
