Thanks! : )
Yes, I used NW 10.5 but If you have a lot of ressources in your game, you should wait. Node Webkit has serious troubles to launch games on Mac/Linux featuring around 500 files and you'll be super busy wasting hours and hours of your time doing tech support for your players. (also, Mac+Linux sales are like 1% from my total sales)
When I wrote this tutorial () , I had nor multiplayer nor translated graphic ressources included. Adding those few files now make it irrelevant even for my game.
I won't lie, I'm very pissed at Node Webkit (tried any version of it + any version of C2) for not being able to launch properly a medium sized projects on Mac and Linux. It's like, sometimes it loads, sometime it doesn't, on the same hardware. Good luck to face your customers, and to sign any Mac or Linux deals or any partnerships with that in mind.
I guess this thing is only made to package small web apps as .exe files and nobody cares because nobody ever tried to export a medium sized game with it in their team. And if one day they fix this issue, you'll be stuck by Greenworks not working on latest NW versions, so...
So, my advice would be to only focus on the PC version for now, really. NW 10.5 works great, achievements support works great as well, simple life.
I wish I never tried to sell the game for Mac and Linux and sticked with PC only.
On the other side, if your project is light enough, just go for it and forget everything I just wrote! Everything should be ok!
until you update it with more content and translations.
