Hi, no, don't worry, the project is not cancelled, it's just taking longer than expected.
Also August 9 2019 isn't the date in which it should be released the v2.0, it's the date in which the first version of this game was released.
V2.0 will for sure be released this year and (judging by how much it remains to do) it will very likely be finished by the end of September at most.
