On occasion the provided music, a midi keyboard rendition of Enya inspired ethnic rhythms, can be a bother. Likewise, the interface has the tendency to be awkward, but once you get used to it your focus can override this. The load times when opening the game also feel a little longer than is necessary. Though each puzzle is relatively quick to finish, it still would be nice to have the option to save your progress. Your puzzle does still open, however, when you reopen the game. Other than a few slight issues with the design this game comes out as a solid activity for stolen moments, but only if you enjoy this type of puzzle to begin with. For the ripe price of “free” you have little to argue with. Seven out of ten stars.
