You only had a week? That makes it even more impressive! Given that time frame it all makes a lot more sense and I can see why you had to make certain choices (and more importantly, needed to stick to them so you wouldn’t lose progress).
Regarding the issue of the different audience, you could be right. I’ve had a look at the jam comments and they all seem positive so you probably made the right call there. Of course you can’t know how they would have responded if it had leaned more into the VN side, but it’s safe to say they enjoyed it the way it is. So if you were to submit it again for NaNoReNo, perhaps it would make sense to have two versions (still on this same page, of course, but with an additional file).
I’ll be sure to have a look again if you do submit it for NaNoReNo because I'm curious what you'll change and what you'll keep. Not sure if I’ll comment since you already have my feedback and I might not be able to say anything new, but I’ll see.
