Awesome game!!
I got this game on sale figuring how could I go wrong with such a cheap price tag?

Well it's a great game. You guide a glob of mercury through different obstacles and try to get to the goal. It sounds simple but there are tons of gadgets, obstacles, etc that keep the game extremely interesting. The stages are varied and unlike other puzzle games, this requires a lot more concetration and finger tip skills.

The only draw back is that it's hard to play over 1hour without losing concentration. With over 160 stages, it should last quite a while. Replay value is really high and that should tell you about the addictive nature.
