This is a phenomenal game! It makes you stretch the ol' brain muscle a bit without causing a complete meltdown. One of the things that I absolutely loved is that all the information is right there. There's no guess work. All of the puzzles have all the information you need to complete them, you just have to be observant. Even the hint system is set up perfectly. It points you in the right direction without holding your hand too much. After I played through to the second chapter, I messaged my friend that turned me on to this and thanked her. If you have ANY interest at all in puzzle games, you HAVE to buy this!
