Query: A bit disapointed

I was very excited to get this for my two sons- but they have difficulty working it correctly. They have taken to standing next to it and stomping the correct color as when they stand on it and shift the game does not register the movement. I will keep messing with it to see if we are having some form of user error- but so far I have not been to impressed.
