When I'm not being a Myst universe fanboy, I'm off being an interactive fiction fanboy. In that side of my life, for the past four years, I've been working on a huge text adventure project. It was a Kickstarter originally. I didn't mean for it to take four years, but hey -- now it's done.
Hadean Lands (http://hadeanlands.com/) -- a game of alchemy, catastrophe, and crashed starships.
This is a serious puzzle game. It's a for-money game; I'm asking $5. (Playable on Mac/Win/Linux, and there's also an iPhone/iPad version.) It's an old-school parser-based text game, which I know is less popular than graphical adventures -- but maybe some of you folks are interested anyway.
Take a look.
