It doesn't say it anywhere but it's safe to assume by how much the game already has presented to us, the developers are probably more focused on finally finishing the game or preparing some major/minor update to the game that's not too far away.
I'm no developer myself but assuming a project is dead when the game already has this much in development provided to the community feels wrong, if you look at the development logs you can see from previous updates of the game that it took about 3 - 6 months for an update to come about.
So, considering that is been about 4 months now since the last update. It's likely a new update will be out around early/late April or May. All I could say is to be patient with the developers, join their Discord for more information or follow their twitter since their last tweet was this month on the 9th!
