Tom Mc Shea writes: Ultimately, Shadow Planet isn't made less appealing because of its disappointing cooperative mode. The single-player adventure is still the most important element, and it is difficult to pull away from this engrossing journey. The minimalistic presentation, exotic visual design, and ambient soundtrack do a wonderful job of placing you in this world, and thoughtful puzzles further invest you in the duties of your diminutive alien. However, small missteps haunt you through much of the game. Mechanical problems distract from the atmospheric wonder, and poor visual feedback constructs an unnecessary roadblock.
