To be honest, after this absurd shillyshally with ch.10, over a year without new stuff, Eva needs to restore some reputation. When she made GGGB, even during very complex chapters, she kept a rather regular schedule. Half a year for the next chapter is simply too long.
We have other high quality, complex games on site, developed by 1 or 2 persons, like "Pale Carnations", "Summer´s gone", "Where it all began", Nothing is forever", Tomie wanna get married" to name a couple, which keep to a schedule of 3-4 months, Tomie gets updated every month, or got faster over time.
