This game made me think a lot! The puzzles did get increasingly difficult as new gimmicks are introduced as well as being tied with old ones. The graphics are crisp and simple and the sound didn't interrupt my focus at all. Although the music does loop, there seems to be a long pause in between. Although there isn't much rewind, I think the act of "rewinding" the stage and the turning motions of the soldiers lends itself to fit in enough. Definitely has the feel of a finished game, and I think other puzzle enthusiasts should give it a try!
