Hello,

I've made the switch to Unity and I'm currently working on a WebGL game, and I'm wondering what options I have for saving player data (scores, settings, etc). I'm hoping to get a suggestion or two. I've NEVER created a back-end server before, and I know that's an option, but does Kongregate allow me to access an external server from their website? Any ideas or suggestions for how to handle saving / the back end of my game?

Thanks,
