I agree that we shouldn't just jump in and support something so fantastic without thoroughly investigating the claim ourselves and that even a simple proof of concept demonstration of my physics engine would go a long way to building confidence with my supporters. It is obvious that I am not ready for that demo yet, so apart from the physics engine, what else is there about the abbreviated GDD that stands out to you?
