Compo Complete!!
Whew, what a rush.
Since I started Saturday morning, I'd had The Compo in the back of my mind as an option, but over the last six hours, that went from a dream to a reality, as more and more features were put into place.
The lack of advanced graphics is key, I would not have been able to do 3D Modelling on top of all this.
My game is up now, at https://ldjam.com/events/ludum-dare/46/mad-antimatter-mania!
I'll be updating it with alternate platform support over the course of tonight!
