Hi there samapatti!
The linux versions of the game can be a bit temperamental at times.
Sometimes the Game.desktop shortcut that is generated from the build decides not to work on some distros.
Try shift-clicking in the folder of the game, and click “Open in Terminal”, then type “./nw” and hit enter.
If this does not work, try making the file executable by running “sudo chmod +x nw” in the same terminal, then “./nw” again.
If that does not run the game then, the terminal should at least provide some insightful information to what else could be going wrong.
I’d be happy to provide any further assistance either here, or at our discord here!
Thanks for supporting us!
