Eitr is not out yet, the devs are incredibly dedicated to delivering on their vision of the game, and it just isn't at that perfect point yet. I have been hype for this game ever since I first heard about it in 2015. I must say that even to this day, it still makes me excited to know this game will eventually come out. The devs have not abandoned the game, they are still diligently working on it.
To anyone that might feel burned by the fact it has been pushed back so far, as a fellow fan I ask that you please be patient. Making video games is hard, especially as a small indie team. I'm personally thankful they don't have a big corporation breathing down their neck to cut corners in order to hit a release date.
To the Eitr Devs, know that there are still plenty of fans still very excited to see your game come out. Best of Luck!
