A raycasting first-person shooter written in COBOL

On a related note, what about a raycasting first-person shooter written in... COBOL?

Can you think of a better programming language than COBOL to implement an FPS from scratch? I know I can't, so buckle up and enjoy what can only be described as an out-of-body experience for COBOL enthusiasts as I set out to make a Wolfenstein3D-like raycasting based FPS game (and potentially go a bit further than that, hopefully it's not a DOOMed attempt).

I don't link to YouTube videos very often, but there's always the exception that proves the rule. The COBOL code's available on GitHub.

What a mad man.
