hey bro i think i have solution for this issue. I for myself wanted to do some javascript stuff and finally also a webgame, but due to my sickness i had concerns that i couldnt' provide an exe as well, (i have tourette syndrome since i was born, therfor anancasm or compulsion i dont know if its the right word in english as i speak german natively ) and is stumbled upon this stuff:
Wapper - HTML To EXE by EyeFly its currentliy 90% off
Offliner - HTML Project Localizer by EyeFly
i dont know if you need it really im still new to javascript
HTML2Win Pro by iD01t Productions
i aalso bought this in a bundle it seems to be a bit better overall but as i said i didnt really had a finished html game yet, but it works i tried out all 2 html to exe tools this project localicer just read so interesting thnat i bought it too)
maybe it would be worth the money especially if you only have web games, you could provide an exe for all of them, there seems to be a html to linux tool as well, but thats something is just saw and didnt tested myself
