Short on character and story, this game is almost entirely a collection of word puzzles, specifically of the anagramming sort. If you like word puzzles, you'll like this.
The in-game help system is first-rate and should allow any wordsmith to complete the game without a walkthrough.
The writing is good, at times slightly over-verbose, but never unnecessary.
I was slightly confused by the intro: it took me a little more time to puzzle out the difference between the gadget and the slider, and why I'd take one and not the other. I think it could use a little more exposition earlier on. It may be a minor spoiler, but I think the game would be improved if the player knew early on that (Spoiler - click to show)the gadget is easy mode--the slider is hard mode. You can probably complete the game with either, or neither, if you're adept at anagrams, but it'd be nice to be able to swap between them mid-game, so you could start with the slider & switch to the gadget when under extreme duress.
If you can't wait for the Sunday Puzzle by Will Shortz on NPR each week, this is a game for you. If you're more interested in character/narrative driven story experiences, you'll probably be less enthusiastic about this game.
I love the word-puzzle aspect, and am glad that I discovered Schultz work via InfoComp2013 and 3diopolis.
