My theory is that our dear author decided to tune her (considerable) talent to "good enough", while we are used to "excellent", and in the beginning it was set to "outstanding". This would make easier to keep the four updates a week rhythm and free some time. I'd very much prefer two or three pages per week, but done with more passion. Of course that would extend this adventure for a longer time... It's true that even in "good enough" mode Minna is very good, way better than the average webcomic, but it's also true that I miss those pages so beautiful that could be made into a poster and hang on the wall.
