This Andrew Schultz game builds and expands on one of my favorite Schultz games, Threediopolis. If you haven't played that game, you should try it out first, as this game contains spoilers for the basic concept of that game.
If you have played threediopolis, (Spoiler - click to show)this is the same sort of game, except some chess-like moves have been added, h,i,j,k. Each of these teleports you 2 spaces away in each direction. For instance, h teleports you n,e, and u, while i teleports you w,s, and u.
This makes the game more difficult. I found it helpful to read some of the documentation on the spring thing website, which will most likely be included on IFDB afterwards. It gives a helpful list of the results of 2- and 3- letter combinations, like hi.
My rating of this game is certainly subjective. The puzzles appeal to me as a mathematician because I love the interplay between freedom and constraint. Emotionally, it draws you into an exploratory/puzzly/celebratory mood. The game is definitely polished, and I plan on playing again (it's a long game, and I've only played through part of it. It's the kind of game I feel I could return to frequently to play around with). I though of taking off one point due to the lack of descriptive text, but I realized that more text would make the game difficult and tedious. The scarcity of text is a necessary part of the design.
Like I said, this game will only appeal to a certain group of people, so I can't recommend it to everyone. But fans of crosswords, cryptograms, and codewords will enjoy this game.
