I finished black plague, and got deeply sad when I heard you cut out the third episode. Black Plague was great but was unfortunately way too short, even shorter than Overture (at least I think so).
I hope you won't change your concept in your next games, intelligent puzzles in another type of game than the traditional point&click adventure game is awesome. Intelligence needed to play games lowered each years and it's nice to see that some guys won't dumb down their games so that everyone can play it.
I know you are working on a engine rework, let's just hope it won't too long to see another product
. I'm a game programmer myself, worked at Ubisoft and since then I would do anything to encourage indie developers, aspiring to do the same.
