This game is fun. You get 4 different characters to choose from at first, with each character having his own special thing that he can do, and the object is to go through the different levels to rescue Smurfette, who has been smurfnapped by Gargamelle. He pops into every level to throw an obstacle in your way, but they're relatively easy to defeat. As you progress through each level and collect more gold coins, you unlock more Smurf characters.
The levels themselves play like Super Mario, hopping onto little enemies, collecting coins, jumping onto platforms, etc.
All in all, not a bad game. Fun for the kids or the kid at heart who grew up watching the Smurfs on tv.
