Chemin HD: update about a great puzzle app game

Not long ago I wrote about Chemin which is a topology type puzzle app that's pretty much the same thing as Numbrix.

Recently, Chemin HD came out. The key thing about this upgrade - more puzzles.  250 altogether now. And a bigger grid size.

Chemin HD will probably make it onto the List of Best Puzzle Apps of 2013.  That will be posted Deceember 31.
