Big Evil Robot

A city is upside down. The people are running, cars crashing and the only guy who is able to face the walking robots is a small boy with a sling. Where is an army useless, few stones make the job. Your task is to hid the core of every huge robot. This destroys them and you can move into the next level. To get into the inside of the robots is tricky thanks small mazes inside them. The game is good but I was hoping for more challenging tasks.
