We all know the principle of these games, find items, use them in certain situations, etc. This one is very interesting because we play in different places at different times. What we did in the past changes the future. The idea is very interesting and we let very quickly take the game. Some puzzles are sometimes farfetched but it is playable in all cases. The life is good even though we would for once have a real long game that would take us about ten hours, which is not the case here. I recommend for fans of adventure / puzzle.
