A better Linux port is needed. Without .exe and without mono.
And _without_ exporting system environment variables that might be used for sth else, you know.
Please, for the sake of Linux (and anything else) compatibility and for performance, DON'T use C#. Just don't. It's a pure poison from Microsoft. Ruined so many games' compatibility I can't count.
An AUR "zerok-git" package would also be quite nice.
