That's fair. I need to have a proper think about whether I branch or not.
My plan was to branch the main storyline (into two) and add a bunch of variations to keep it interesting for anyone wanting to replay it, but I also wanted to try to make a game where everyone's experience was slightly different.
As for lewd scenes, you can currently see every major lewd scene in one playthrough. But there are failsafes built in so that depending on your choice to pursue certain LIs or view certain content, there are alternative scenes to ensure the story keeps it's continuity. The choices you make also affect the outcome of later non-lewd scenes, so dialogue/actions/reactions/locations changes depending on choice. Stat checks unlock minor variations to lewd/non-lewd scenes, and you can't currently pass all of these in one playthrough.
That's basically where the game is at in it's current state
