Hi again, I released an update for the game, with the addition of an exit button and other features with bugfixes.
Thanks for the reply and your work.
But it seems only the Windows version was updated ... and I am using GNU/Linux (as visible by my avatar ;) ... so can not check right now ...
Oh sorry, my bad 😅 I thought your friend was on Linux. Anyways, I added it in the Download section, it is available now!
