PuffBOMB

Description
PuffBOMB is a free physics based puzzle game somewhat similar to The Incredible Machine. Using the mouse, you place and set the delay time on bombs. The bombs are used in turn to push hamster(s) to a goal. Of course, the bombs cause the hamsters to ignite, resulting in hamsters screaming and using some mild language.
The game includes eight standard levels as well as a level editor, to make your own maps. Nearly a dozen user contributed maps packs are available.
