Cute and fun puzzle game with varying rules in each level where you have to figure out which body part(s) will help or impede your party of 16 diverse Zoombinis in their journey onwards to Zoombiniville. My favorite levels were Captain Cajun's Ferryboat, Titanic Tattooed Toads, Lion's Lair and BubbleWonder Abyss. I did not encounter any bugs on Win7. Game speed is a bit slow and may lend to more frustration especially when one can't seem to figure out the rules for various levels (i'm looking at you Mr. Pizza Pass Troll!). I'm looking forward to playing it on harder difficulty levels.
