Help Harry to find way through many traps and booby-traps bu using and combining things from your inventory. During each level places are marked , showing where to use on of the inventory object. After placing all and hoping it will work , you start the reaction hoping for success. Of course you can only guess if for overcoming the wall is better a balloon, cannon or some dynamite. It is clear that after some levels the difficulty increases and so finding the mistakes and correcting them is more and more challenging. I am very happy with this game but still thinking if it is more logic game or adventure.
