I guess I'm telling what everyone here is probably already aware of, I'll say it nevertheless.
The splendid guys from "inkle" have updated their Sorcery games (all of them), to include a new "super hard" game mode, which you can unlock after you have finished part 4, and which starts at part 1 all over again. They say there are some secret areas to unlock as well. Somehow the Sorcery games and the dedication of the developers remind me of "King of Dragon Pass ", in a good way. You really "feel" the developers love their work.. A big Kudos to them from my side.
