I suck at these kinds of games! No, not revolution ones, I don't have a steady mouse hand. And this game, ugh- with that growing and shrinking set up right from the beginning, it's truly more challenging than most of these games. The only exception is that there aren't too many of those incredibly narrow passageways that you can't navigate easily enough.. if your timing is right. Take it from me, don't be swelling up and try to take on the elevator like stage.. This game will be an instant hit, and game you'll love to hate- if you're like me, and hate losing to such a simple game!
