A good game to train your brain sometimes, it isn't too difficult but also not quite as easy, if you learn from your mistakes, you'll eventually figure out what to do. Mostly it will involve "5" curves and trying to fill some blocks from the beginning rather than on the way to the end.
Graphics are smooth, darker tones are pleasant for the eye and overall not too constrasting so your eyes won't hurt (unless you're too close to the screen staring blankly at the map figuring out the path.
Overall I enjoyed playing this game, a little simple but that's not a downside for this type of game.
