Block Line Engineer — is a physics-based automation simulator game in which you build machines from basic parts such as engines, rotating joints, and connecting plates. When your machine is ready, you teach it to move and perhaps combine it with another machine to form a line of blocks. Block lines move blocks to block recipients. Optimize block lines for maximum bandwidth. Both machines and units are modeled to mimic real-life physics. Machines must be driven by engines. Links to which many parts are attached are heavier.
