Like all games from this developer, this game is worth checking out. My only complaint is that it's confusing at first because you just begin the game right away without any introduction or tutorial. When I went back to the store page and read the description it explained part of it, and when I played for about 15 minutes I finally read the digital display on the train and then I understood what I was supposed to do. The anomalies are mostly very subtle, and that made it more difficult for me to figure out what I was supposed to do. However once I started paying closer attention it was fun picking out the subtle ones and doing a double take on the larger ones. Recommended! I purchased this game and two other from this developer in a bundle, and I have enjoyed all three. Try out a bundle!
