The puzzles are consistently challenging without being frustrating, making for a relaxing and rewarding progression through lushly designed environments.Unfortunately the story, which was the main draw for me, is completely indecepherable due to the use of gibberish language. I'm sure the game's designers knew what was going on in each of the scenes between levels, but I sure don't! I can't even really identify the characters well enough to follow who's who, let alone what they're meant to be saying/doing in each scene.The iPad edition is by far the best one, as there is plenty of screen space for the pinch/zoom gestures, and the graphics really shine. It's OK on iPhone, too. On Mac, the multi-touch gestures are bafflingly unsupported, forcing you to play with an awkward set of click-and-hold gestures that ruin the moment-to-moment experience.I hope they'll add multi-touch trackpad support to the Mac version, and consider adding intelligible voice acting, subtitles, or some other way to follow the story.
