Besides following your commands, the robots have a kind of personality and will react to your commands better or maybe not at all. That depends on their mood, which is being displayed at the left bottom of the screen.
Quarry is not really a grown up game, because it really is short. Nevertheless I added it to the review-section because of its uniqueness in gameplay and design. This is not your average puzzle-clone you already played a hundret times in different appearances. The robots are very well modeled, the levels are beautifully designed in different seasons. The idea of giving the robots an AI which is rather "bitchy" adds greatly to the gameplay.
This game is a piece of art, which could easily be extended to a whole exhibition, but at the moment only consists of six tableaus. I really enjoyed watching the little robots and trying to coordinate them to build them their stairway to heaven ;-)
