Physics games have been given life with Assembler. In this game, the objective is to fit the 'key' square in to its proper location. There are also other boxes that are used to help get the key square in to its spot. The game is made more difficult with the realistic physics and it will take a while to master. Use your mouse to lift the boxes in to the proper places. Don't worry, each level is harder than the previous and it will require some planning. If that weren't enough, the developers added a timer and you have to complete the level as quickly as possible. Go ahead and try it out.
