This really isn't a game so much as it is a sort of experiment in platforming backgrounds.
In past projects, on other platforms, I've had to use a variety of weird techniques to achieve the "paralax" effect. So when I found out about the 3D Box object in Construct, I decided to see what could be done with it.
The result is the discovery of the ability to make some primitive 3D backgrounds, with the only limit being the cubic shape. On the bright side, you can change their Z position to make the objects further away, and they move properly in relation to their position.
I really hope there are other 3D primitives supported in the future (simple spheres, cylinders, etc.).
