Thanks for the SBI/HBI share!
My world/game is web based too, but the graphics are super simple. Unity is a great game dev platform and I may use it in the future, but for now my game is simple enough to not need it.
I see your url is http. I have my browser set to warn me of non-https sites so I didn't go there yet. But I will go there on another computer or Virtual Machine. Are you thinking about getting an SSL Certificate? They aren't cheap. I use the Free Cloudflare plan and get their caching, security and https for free. https://www.cloudflare.com/ssl/
Yeah doing SSL is the goal.
We had SSL when we hosted on Heroku but since we moved to AWS something messed up with it.
Still working on it, but did not want to delay the relaunch over it.
