Save weird creatures, who have fallen into a trap on a seemingly abandoned planet. To do it you must solve a puzzle, which opens cages. When you hear a click of cold steel, you can be sure the old cage lock opened. Don't be afraid, if you couldn't solve it. There is a nice help available. However, this is only a part of the story. It counts how many clicks you do in each level. The look of the monsters evokes crazy fun and creates a smile on your face. This all is coupled with nice moody music.
