I'm not quite sure I understand what IF means though as long as the story is interesting and character aren't one dimensional I'm sure I'll enjoy the final product. Either way good luck I hope there are no roadblocks ahead.
IF means Interactive Fiction games/books/VNs/html(like this one).
I highly recommend the Tumblr page: Interactive Fiction. They have rec lists and repost a lot of works similar to what you said you enjoy.
I mean, I'm all for IF as long as I can heavily control my characters personality.
Me too, I really like to have control over the MC's appearance and personality,
Yeah too bad it's too much of a hassle for most developers to make the story branch that much.
