Sorry to burst your bubble, but you're wrong. He had goals of ep 13 being out October 31 2023. He obviously missed that. So yes, the update was supposed to be ready before the last update.
Most of episode 13 is releaed already tho. B3 was released in February, B2 and B1 somewhere before that. Just because he didn't deliver on his promises (E.g. up to his own and your expectations) doesn't mean he didn't deliver anything. As I said earlier, if you ignore what he says this is a perfectly enjoyable VN. The expectations are the problem. Just going with the flow is much more enjoyable.
So you didn't burst any bubble. I don't have any delusions about him. Just a different perspective that results in me not malding about trivial things.
