FOSSIL ECHO is more an interactive cartoon than a platformer. Graphics, animations, music are good, but you'll spend more time as a spectator than as a player. Your character wakes up, then you move right : animation. You approach another character : animation. Then you enter a door : animation. The platform phases are... the exact term is : boring. It's repetitive and finally not rewarding. The difficulty is medium and depends exclusively on the timing. Generally you have no second chance when you fail - some elements disappear and you have to kill yourself... The stealth phases are equally boring, the pace isn't mastered. Two stars for the graphics and animations. Only two stars for everything else.... (note : I win a key of this game and had not buy it)
