I liked the James Bond-esque theme of this one. I got a bit stuck at various points (I was convinced that you were supposed to lead the dog to the lonely henchman, so spent ages trying to get the former through the portal), so did need a quick glance at the walkthrough at times. This was also partly because there are several objects that can only be examined when they're in your inventory - I had already examined them before picking them up, so didn't realise they needed to be examined again once carried.
Something to fix - you can pick the chest up and carry it around, but can only oil it when it's dropped back in its original location. It should be scenery rather than an object.
