Based on what I had seen and based on how much work you are putting in this route, I can tell it will be the best of the 3 released, the anticipation for this route for me is quite strong!
Also, please don't worry about how long it is taking to be released. You are putting so so so much work into this sequel. So much work into this route, I do not think anyone will ever fault you for taking a bit longer (and no one should, in all honesty.) and it makes sense, this is a pretty big route.
Thank you for the update, I hope you are doing well!
