Yeah!!!! I've done it. The last one requires some timing which is very hard to do with a stupid laptop touch pad! I'll give you a tip for the last level. Take out the cat first, but it takes a number of steps to do it. The very last bit takes some patience as you have to click the spring at just the right time. Good luck!
There are two halfs. In the first half you have to get the man to come out of the blue door and then drop the bucket on his head. When the old guy shoots the bullet will hit and break the camera. Does that help?
