This is actually very nice.
I'd just like to point out as well, that unlike many other similar attempts it is is not based on pygame, and does not suffer from either the flakeyness nor installation irritations that comes with.
Instead it implements a very minimal (dependency wise) custom layer on top of glfw.
Many people will be skeptical of a python game engine, but I would recommend this one over many others.
Limited in scope and very good at what it does.
