Machinery2 - Physics Puzzle

Continuation of the game Machinery!
Machinery 2 is a physics game where there is no single solution for passing the level. In any level you are invited to find your unique solution.
In this physical puzzle there are only two basic shapes, a rectangle and a circle.
But the possibility of scaling, rotating and combining them together makes it possible to create any mechanism or apparatus.
* New levels!
* Now you can build mechanisms in two layers
* New type of connection "Fixed connection"
* Added stars. Three levels in one!
* Added timer. Optimize you solution!
If you need a car or some machine to solve a level you can build it! Just use you brain! :)
Hinges or motors are used to connect shapes.
The game is designed in a 2D world and have accurate and realistic physics. Zoom in and out by pinching the screen and pan the view using a two finger drag.
It's time to remember the laws of classical mechanics!
Check your brain for creativity and ingenuity!
