Thanks for your opinion, but honestly, I work on this game in my free time. I'm not a studio with a team of people, it's purely my own project and I decide where the story goes. What you suggested doesn't really concern me. It's my game, and your ideas don't have to match what I want. If you don’t like the direction it's taking, you don't have to play it. No one's forcing you.
I released the update as soon as it was finished. The date you're seeing is most likely a bug or a technical glitch, nothing more. I didn’t delay anything, I just work on it when time and motivation allow.
