OpenGL is free software though possibly underlying CUDA is not. We
started work on it here:

  
https://github.com/Brainiarc7/guix-bioinformatics/blob/master/gn/packages/cl.scm

but never got it to work properly.

Yes, and worse, there is no guarantee that they are the same on a
user's system. What you want is a reproducible setup.

I think packaging your game with OpenCL is possible with GNU Guix. You
can ask people here how they are deploying their software.

Distributing the game is possible too. Even installing user land
directories - using my installer

  https://gitlab.com/pjotrp/guix-relocatable-binary-packages

would be straightforward to accomplish.
