It would be nice to be able to work through a series of puzzle increasing difficulty from 0-4 without having to go back and search through the main puzzle menu to find the next one. Or is this already possible?
It might be interesting to experiment with varying the default sort over time, and seeing if players going through the present way might have different insights from players that played series in order of increasing difficulty. Since not everyone seems to be walking through the default order as I did, maybe this question could be looked at now. Is there info on the order of puzzles completed by players?
