I just tried that, and it effectively launched the game, along with giving several error messages that seem to be inconsequential in the end.  It looks like it also downloaded some missing components, as you can see here :

This does look scary indeed, but like I said, the game launched and actually worked.  I closed the game and re-tried that command, and as I suspected, there are the some of the same messages appearing again, but some that didn't (i.e. those that were associated with downloading updates).  The game works, including sound, despite these remaining error messages.

Hope that helps.

Hi G-9Games, i know that nw.js uses Chrome under windows or chronium under linux to start app. You should have fixed these few errors by following the commands below


To update your actual pkg:
sudo apt-update && apt-upgrade
To installing chronium-browser:
sudo apt install -y -o 'apt::install-recommends=true' chromium-browser
Run one time: 
chromium-browser

You can close the browser and go in game path start the game with:
./nw

Let me know if errors are fix.
Good game

Hi FoorbarIT,

Sorry for the delay.  I just tried these commands, and you might want to edit your post for future reference as there are typos in the first line : there are no "-" needed between apt update and apt upgrade.

The previous error messages about packaging are gone.  Now, I receive the following input just FYI :

~/Téléchargements/Hardware Tycoon (Linux 64-bit)$ ./nw

And the game still works.  Including sound, despite these new "error messages". I mean, at this point, it's no big deal for me, the game works and I'm all happy!  :-)
