Ad Astra per Blastera (unfinished DOS game)

So, there was a mini ludum dare compo dedicated to low level coding. And this was a big thing for me, I really like oldschool coding so I decided to try something. Mainly it was an opportunity to get me motivated working on my new 3d engine (which is just flat polygons and no sorting, clipping or anything now). So, basically you just move left or right with the mouse while cubes are coming towards you, but there is no gameplay yet. I did posted this with source code on the mini ld page though.
