Time, time, time limit, sadly.
I was planning to make one of the arts description change a bit right before the end, to show how the museum changes the meaning of some of the pieces to align them with the events happening outside. In spite of artists who were against that. But I think it took too much attention away from the museum too early, could have made players confused, and or could have been missed unless I made some visual change to bring players attention. But that requires more resources and time.
Maybe in far away future remake of this game, who knows!
