Fun game for toddlers

My 3-year old son loves this game. Even his older sister has a blast of fun although it is short-life.
The game needs to introduce some game modes. For starter, add a mode to match pairs with all open cards, so some toddlers can learn matching pair prior to memory.
It will be great if the developer can create a total different theme like mighty-machine match, boys love it!
