They are making 2 more games. The sequel is called khemia, (Which is going on a small hiatus in order for the story to be developed properly), And The other 1, Which is supposed to be about the events that amicus briefly mentions of touring the moon, Is called Interea. I'm not part of the echo project team, But I hope this answers your question because this is the only information that I know about Since I'm not a patron. Apologies if your question was already answered
