As mentioned in my original post, the developer account on Google Play did respond to one of the reviews, asking the reviewer to clarify their issues. They would not be asking that if they have abandoned the project completely.
This developer is known for being MIA for long periods of time. Yes, this time it has been extra long.
We don’t know what is going on in their life. They could be dealing with mental health or other personal issues. They could have a new baby. Someone very close to them could have been diagnosed with a terminal illness. They are working on the next big thing that could make them 100 million, and set their family up for life.
The point is, sometimes life gets away from you, and you drop the ball on less important things.
