One thing I liked about Despicable Me: Minion* Mayhem was that the game has a ton of stages. In each level, you have to try to maneuver your Minion through obstacles, which vary from teeny robots to humongous spikes.
Sound tough? Well don't worry. During your adventure, you'll find other Minions to help you complete each level. For example, there is a big Minion that makes beating up on enemy robots a breeze.
One of the things that I didn’t like about this game is that it is not that interesting overall. If you have played Mario Vs Donkey Kong: March of the Minis for the DSi Ware Service, then you'll be pretty familiar with Minion Mayhem's point: get your avatar from the starting point to the end point. All you do is lead your Minion past obstacles to a door that signals the end of a level. That's what the whole game is about...
If I were the maker of the game I would make the game more kid-friendly, by adding pictures or clips from the film Despicable Me into the game. And I would also add level editor, since navigating different obstacles in each level makes up most of the gameplay.
*For those that don't know, Minion's are the little yellow troublemakers from the movie, Despicable Me.
