My fellow Dominic was so nice to me, that he relinquished this great puzzle game. From other parts is not changed and remains exactly the same task. Find button, trough which you get to the next level. The problem is that each level before you will build a completely different task or challenge that must be met and thus find the necessary button. Sometimes it is a pure logic, where you are looking for a certain sequence, it is sometimes necessary to use a little finesse with your mouse, or be involved wit. While not an original idea, but design is perfect.
