JS Legend Dev claims this uses Neutralino.js? That is real nice, however...
If it had the option to choose NW.JS instead, to ask if they want it to run in Chromium or the user's default OS browser.
Please make that happen!
yup, JSlegendDev shared this, I've tried it with ExcaliburJS game i made, and it worked easy peasy... very intrested in where this development goes!
