Dummy Defense is a spin-off of the popular physics and engineering game, SimplePhysics. In Dummy Defense, you must use your engineering prowess to protect Melvin, the dummy, from an array of dangers, such as boulders, explosions, death pits, meteors, and more. Using the same blueprints editor from SimplePhysics, the player must build a structure that is simulated using a physics engine in real time. Players can view how their design reacts in slow motion, fast forward, and they can even rewind time to pinpoint any weaknesses in their design. It’s an addictive game with a wide variety of levels, and players may even learn a few things about structural engineering along the way.
