HARRY THE HAMSTER

A cat is trying to catch Harry's hamster, and he, poor fellow, is trying to move from one rack to another. Help the hamster do this by building a pipeline from the materials available at each level. Make pipes, canned food, planks-everything that will allow the hamster to crawl safely and not fall into the cat's paws. Hurry up, the time of each level is limited, however, if you manage to finish the construction of the transition before the time runs out, you can click on the key and get extra points.
