i didn't possibly think you could add much from the first game. but there's a ton more to use to solve puzzles, which takes thinking and a lot of time. it makes you actually use your brain. I love everything about this game, great music by the way, perfect for this game. A job well done. Best puzzler ever. easily a 5/5
just beat game it is amazing kept me entertained for a couple of hours, everything about it is just awesome from start to finish. truly a unique and incredible game 5/5
