they are working on shale hill secrets (and it's engine is bit closer to renpy than dfd's engine) and lj devs could port this to renpy if they wanted but question is why? better spend that time making new content/new games.
Well, if they don't port it to Ren'Py, I won't be playing it. [I'm sure that will force their hand!
] I have too many great games that I'm NOT getting to play, to mess with one with a proprietary engine.
I've gotten a lot more selective since I played this game, and I still can't catch up.
