I have seen many devs become complacent once they reach a certain level of patrons. Delays, excuses and disappearances. No one is immune to charms of success.
Except Eva is about the same level than she was with GGGB, is she not ?
And she delivered with that game.
The fact this one is infinitely more complex and that she's investing money to make the game better (colorist, backgrounds, trying to get someone else to help with art etc) should be a good indicator that she's not in fact being complacent.
If anything I'd argue the last part of GGGB was like that, because the last fourth of it saw the plot become extremely simple.
With each updates of ORS the complexity has been increasing.
I personally think she should take a month to plan ahead. Write down all the options for the next three updates on a board, all the permutations, then restart working on the script once she's happy with it, one update at a time. Gives her the flexibility needed and wanted, allows her to not have to think about the ramifications too much once she's in "writing mode" because that's done and gives more consistency to the game.
Of course, it's easy for me to say this, and it might actually not be practical. But the one thing I won't do, is shoot on the ambulance because I believe in her and so far she always has delivered with the updates.
We'll have that talk again later, I'm sure.
