Brother we're all excited to play the new update, and the fact that they changed the date 3 times now it's a bit frustrating, I get it, but you have to keep something in mind, as far as I know the game is being developed by just one person or a very small team, they also have a life, they also make mistakes, their whole life can't be around developing one game, that could fry one's mind and make them burn out and then it'll take even longer to release.
Personally I'd rather wait a bit longer to have the biggest update yet that it looks that will change the game completely than to have one more update with a few more scenes. Kal/the team is always making/adding new interesting things to the game, new minigames, scenes, characters, places, routes, etc. That takes a lot of time to code, illustrate, make sure the code doesn't get bugs, to polish, all that while still living a life.
It was a mistake to put a release date and then move it 3 times, no one's denying that, but these things happen, and I'm not saying you don't have the right to be frustrated, I'm just asking you to put yourself in their shoes, you want to do a nice update at a certain time but a few things happen, more ideas came, time run out before you realize, you want to give everyone a polished game and everyone is just repeating "update when?"
I'm honestly happy that Kal/the team is adding even more scenes and reworking a lot, seeing that the game will be completed/done at 2.0 and won't recieve any more official updates, I'll always be wanting more of the characters.
