Haha, no I saw the edit after I'd done it and I just had to go make some food.
It's a bit of both. Once you actually start at the school, there will be an initial period where you are essentially just getting to know the girls, playing through their events, having to protect them from certain things etc. There is an overall plot which will be kinda always present and assuming I don't completely fuck it up, will weave itself in with the characters as some of them are connected. The way I've tried to tell the story so far is quite intentional. Make no mistake though, while there is a story, and it is something of a mystery, my main focus (And thing that I'm hoping will set my game apart) is the quality of the H scenes. I'm trying to make them as good as I can.
I've always kinda hated it when there a game I like, and then you get to the h scenes and it's just no sound, 1 second animation loop and then the MC says "I'm cumming" and the scene is over. I'm trying to avoid that, but I'll admit I've got closer to that last part in the content so far than I'd like. Early days I guess.
I was a big fan of Once in a lifetime though, and while I don't think I'll be going as story focused as that game, it is something of an inspiration so I'm hoping to include some similar elements.
(Essentially to sum it up, it'll mostly be just having fun in school for a while, but there will be a point where the story kinda takes over and it becomes more linear again. I just don't think there's really a way for me to write in the kind of content I want to include for all the different girls without doing it this way.)
