A decent start of a foundation that could lead to a lot more. The concept of breaking a child's toy begs the question of "what next"? Do the children run to their parents and you then have to evade the parents until they get tired? Do the children go into a blinding rage and chase you themselves with murderous intent? What greater purpose am I serving as a dude breaking kids toys? If there is no greater purpose than just being mean to kids then where's my mean-o-meter to tell me how awesome I am at being a meanie?
The premise is interesting and not commonly done, but it would definitely be interesting to see more come from the interactions you have in the game.
