I was very surprised that the laughs were so corny and forced. The laughs don't come with every touch. More often than not you get a faint pale colored letter, number, or shape with no sound. My 18 month old said, "mommy, I don't like this."
I guess we have higher standards.
To the creators: I suggest having the name of the letter, number, or shape said in-between giggles. Maybe hire some actors or other children whose "giggle" doesn't sound so forced.
