If You like classical logic games here is one you were looking for.
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.
The early levels will teach you how to play the game and go through some basic concepts.
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!
