i tested your game on Linux Mint: it worked.
Filenames would be better as cyberdunk_linux.zip" instead of just "linux.zip"
On the game itself, I have to agree with Emiss23.
The levels and enemies are not very interesting. It is just cube-shaped rooms and a bunch of post-processing effects. It felt more like a techdemo than a proper game. In the first level when I pressed F to go to the next floor, my crosshair disappeared. Is that on purpose? On death, the camera floated endlessly through the walls.
