I believe 0.38 -> 0.39 took a year. Voreronika hasn't said anything since late Feb. on their Patreon, and their Eka Portal page no word as well. I know Voreronika said somewhere they have a full-time job and the person(I don't know if they are a he or she) had to do some overtime work as well. So I'm guessing the developer just hasn't had time to work on the game.
The negative with games like these, if a developer gives no word for a long time(many months) then it's a possibility the game is dead. You just can't go something like 6+ months without much said and expect the game to still continue.
