As you might have heard from elsewhere, I've been asked by the author of In the Company of Grues blog to design and code a game that would be suitable to teach newcomers how to play IF. This is a pretty sweet deal because we're having the entire development process completely transparent. The development wiki is at inthecompanyofgrues.com/iftrainer where you can see how the game is coming along and leave your own comments.
We're aiming to release at the beginning of September, in time for PAX Prime and before IFcomp starts to avoid being overshadowed.
