All. The Music, the environment, the levels (which in the second half of the game are put some something heavy, and start to be more puzzle through platforms), mechanics, history and its mystery... I love it. I spent it in three games. From the first to the second passed as half a year, forgotten, being the last of the queue on my list of importance. But a summer day in which there is no importance, I went and finished it. The first time I had been in love with much of the game, but before I even finished it I knew it was going to be my favorite. The music is to my liking, but that means nothing to you, the read it, because my tastes are rare. Sometimes it gets very heavy as it repeats and repeats, or maybe there is a strident synthesizer that makes you go crazy, but otherwise it's all good. The mechanics is very simple, you take a photo and when the Flash is finished you mount a solid shadow that you can step on. The timing of the flash is getting more accurate as you go along. The levels at the beginning are very tutorial, I don't remember the first levels but it does make you learn for yourself most of the time. In the middle of the game some of Them get pretty heavy, because of the precision, maybe, but they always end up and reappear again. Then a part of the puzzle is added. Although I do not mean that owe play the game, because I am a madman of this mysterious theme and that makes wait for literally the last moment; But yes, I recommend it for everyone. Recommended for people who like challenges, the second half are doing very well. Better buy it in a pack.
