I plan to add bullet for the physics, but before the graphics part has to be kinda comlete.
And well, this is meant to be a simple example level on how to get things running without anything more complex than needed.
You can already code whatever interaction you want, but this hasn´t much to do with the engine.
This is just about the engine and not about game mechanics

The next feature will probably be stencil shadows.
