Install TmNationsForever snap on headless server


I have a special request and hope that you can help me. I saw that Snapcrafters made a TmNationsForever app. I’m running a headless Debian11 server and need to install the game on it. I know it sounds a little weird to install a game on a server without a screen, but I basically only need to be able to start it with start arguments, not actually play it.

So I wonder. How can I possibly install the game on my headless Debian11 server? Can I do it with snap or would you recommend me a better way to accomplish my goal. I have no experience with snap or this kind of stuff, so I really appreciate any help I can get. I believe I’m not getting around installing a GUI for the installation process, am I?

Thank you !
