i think you should try this:
export game as html, open visual studio 2015 (not "15", that's an old preview version), download newest (google download visual studio community).
when installing make sure you install CORDOVA tools, you can also find them on
then open vs, start new project - cordova html app. once created make sure you import your files into that project (not gonna go in details how, figure it out youself )
compile and run = gg wp.
if you want to add crosswalk over it, you can through plugin manager, it will install automatically and all set up. you can then add the "fixes" for ignoring blacklist and so on..
compile again and you got your game with crosswalk.
oh yeah, that's for android & ios. if you're doing UWP then running the solution file should work.
