I think the dev is making a huge update because it is taking along time but I'm willing to wait because I love the game and the storyline keep it up
I was told Arc's reworking the battle system in addition to the new content. Reworking the combat is probably time consuming! Given how great everything has been so far, I don't mind the long wait (even if it is hard to wait...)
so that is why it is taking so long I'm already getting excited for the update thanks for the information
