Brilliant, innovative parser-based interactive fiction – Hadean Lands: Interactive Alchemical Fiction Review

To get this out of the way: this is IF/text adventure, but it's not about solving mazes and playing guess-the-verb. It is about intricate, fascinating puzzles with a unique iterative mechanic that gives you a sense of mastery; a detailed, coherent alternate universe based on alchemy; and an overall meta-puzzle as the player tries to figure out what happened, not to mention who he/she is. Innovative parser commands streamline gameplay so you're thinking about the game, not the mechanics, and the iOS interface gives you an interactive map and journal, as well as multiple ways of minimizing typing. The game is a joy to play, but fair warning: it swallowed up an entire week of my time.
