there been delays since 2019. It is almost 2022, I don't know how many times the game was given over to a different publisher, but it seems like whoever is working on the game is extremely lacking the ability to actually finish it in a decent amount of time.
I just going to say this once, if it was for free then of course taking as much time as needed is OK, but once you start involving money then you are entering territory where there has to be some accountability. I hope you can get through all the trials and tribulations, but if after all this time the full released expansion does not introduce a bunch of new things and just ends up having repeated dialogues that you seen before in other routes.... basically if someone can finish the two new routes in just 30 minutes-1 hour then whoever is working on this should be ashamed for making their supporters wait sooo long for just a just bonus content.
In conclusion, be honest with consumers instead of giving misleading information or unrealistic release dates knowing the work ethic isn't there. If you want to see what it means to be honest with consumers then look at the post from the developers that made "The Divine Speaker" on itchio; they give a break down of everything going on and why the game is not released and honestly say they can't give a clear release date. It shows true respect to their consumers, and no one will be upset because the content they have released was completely free.
Sorry for being harsh, but it has to be said. I don't think other people should completely turn away from the game just because of this. However there needs to be some accountability.
