Your mission is to build a machine with physic entities to collide yellow elements. In the build area, you can build with rectangles and circles elements. You connect them with rods, 4 types of joints are available : weld, rotate free, engine clockwise, engine counterclockwise.The faster, smaller and lighter you complete each of the levels, the more bonus points you receive.Features:• more 60 levels• Physics based game• Freedom of construction• Rectangle and circle elements• Rods with 4 joints type : weld, rotate free, clockwise, counter-clockwise• MultiTouch Support• Multiple solutions for each level• New free levels every week• High scores• Music 你的任务是建立一个机器物理实体碰撞黄色元素。在构建区，你可以用矩形和圆形元素打造。你与他们连接杆，4种类型的接头可供选择：焊接，逆时针旋转自由，发动机顺时针引擎。更快，更小，更轻，你完成每个级别，您将收到更多的积分。特征：•更多的60个关卡•基于物理游戏•建设自由•矩形和圆形元素•使用4节连杆式：焊接，无旋转，顺时针，逆时针•支持多点触摸•每个级别的多解•新的免费各级每周• 高分数•音乐
