Cant use it with kids anymore

As a science teacher of 4th graders, I used this along with my engineering unit. But with the addition of the Bomb Shelter level I cant allow it anymore (teachers cant have simulated bombs blowing up simulated people in iPad games- and there is no way to keep the kids away from that level). It is a shame, because it was a good app without that level. Parents who want a non-violent game should also beware - since it has now gone over to the "dark side." Too bad.
