PixelJunk Eden is an oxymoron. Everything about Eden hammers into you, scribbling across the surface of your eyes and penetrating the depths of your ears to produce an experience both lucid and surreal. So what the hell happened? Eden is clearly a game about exploration and platforming, one that eagerly illustrates relaxation. However its entire concept is thrown right out the window because a design choice was made to include a timer. A timer in a exploration game (a platformer no less) emphasizing calm. Truth be, Eden is an exercise in controller twisting, teeth grinding, frustration. It's beyond the point of challenging because the sloppy inclusion of one mechanic destroys what could have otherwise been an incredible and soothing game.
Normally I'd detail my feelings, being so negative in nature, but straight up I don't think you should buy this game. I suppose if one enjoyed the demo then the complete product might be a consideration, but the bizarre inclusion of a single element becomes ever more prominent in later gardens. In short some might find Eden a challenging experience, but I am confident most will just delete the game in frustration before long.
