Do you like tinkering with various mechanisms? You always have to know how that stuff works? And what if you have to devise a mechanism to destroy the robot somewhere in the level? Can you post correctly bombs and other objects to take action, which results in destruction? The authors start you on a little help and direct how the bomb works and how much can be done with them. Then, however, the player must cope alone. You will find all sorts of things that can move - a circular saw, a cannon ball, blocks responsive to magnets, etc. You only involve logical thinking. Or try out your idea in practice. If not correct, feel free to reset the level and try again.
