There is so much lack of professionality in the crypto world: turning off a game with almost no advice and after having sold assets untill a few days before seems like almost a rug... really a bad behavior from these developers :/
I'm sorry for you, as I know you liked that game a lot... I hope someone can take the project and keep it going, somehow.
I have to say this one does really feel like a rug pull - pretty poor behavior. Even the wording of the announcement is in poor taste. Not impressed at all. Heres hoping it can be taken over - but I doubt it will happen.
