when the next update? is there daily update set?
The game is not going to be updated for a little while. The project is currently on hold due to a lack of inspiration (so I've heard).
The writer is writing another game happening in the Adastra universe:
Adastra "Interea" (receives monthly updates)
Interea focuses on events that are only summed up in Adastra. Therefore, you'll have to play Adastra before playing Interea, or Khemia (Since Khemia's a sequel to Adastra).
