Hm... I'm not sure your solution is the solution to the problem I'm having?
You seem to be solving the problem of "games don't load if there's too many files because the current build of NW.JS is dumb" and I'm not sure that's the problem I'm having. My game is relatively light, and this is the first time someone's had a problem with this Linux build (and expressed it to me anyway).
This problem seems to be with a missing Chromium package? I'm honestly not sure, I don't know what the error message means, and I don't understand why something would be outright missing.
I know I *should* have a computer running any OS I plan on distributing for, and I know I especially don't have an excuse for not having Linux, but I honestly don't have a good enough understanding of computers in general to know what I'm getting into. I may look into getting my laptop to dual-boot, because it's already got half a foot in the grave and I won't be devastated if I mess something up. I just know I'm going to break something. heh...
